Black Bag (Universal, 4K Ultra HD + Blu-ray, R, 93 min.). The sophisticated film deals with members of an unnamed British spy agency that probably has a leak concerning the Severus Project, an abandoned means of melting down an enemy’s nuclear reactor, resulting in the deaths of thousands. It is left to George Woodhouse (Michael Fassbender of “Prometheus,” “X-Men: First Class”) to uncover the traitor within one week and the suspect list is down to five names, including his wife, Katheryn St. Jean (Cate Blanchett of “The Lord of the Rings” trilogy).

While Woodhouse does investigate his wife and the other four possibles, he is fiercely loyal to her and will do anything to protect her. The other four are the agency’s in-house shrink Dr. Zoe Vaughan (Naomie Harris of “Moonlight,” “Skyfall”), agent Freddie Smalls (Tom Burke of “Furiosa: A Mad Max Saga”), agent Col. James Stokes (Rege-Jean Page of TV’s “Roots,” “Bridgerton”) and data scraper Clarissa Dubose (Marisa Abela of “Rogue Agent”). Smalls is still upset that Woodhouse promoted Stokes over himself. While Smalls is dating Dubose, Stokes is having sex with Dr. Vaughan. Overlooking them all is Arthur Stieglitz (Pierce Brosnan, with spy experience in the James Bond films, including “The World Is Not Enough,” “Die Another Day”).

Woodhouse starts his investigation by inviting all the suspects to a home-cooked dinner. The dinner only reveals the cracks in a couple of relationships, with Smalls getting a knife through his hand.

The winning film, directed by Steven Soderbergh (“Sex, Lies, and Videotape,” “Traffic”), recalls the British Cold War spy films, but has modern touches with satellite surveillance and drone strikes. The screenwriter is David Koepp, who worked with Soderbergh on “Kimi” and “Presence.” Koepp also co-wrote 1996’s “Mission: Impossible.” Fassbender was just off the 10-part TV series “The Agency: Central Intelligence.” Much of the film’s spy versus spy is through dialogue, which often is quite snappy. The term “black bag’ is used when one cannot disclose details of a secret operation.

Extras include three deleted scenes, including another death (6:24); a look at the actors and director (10:12); and a look at the locations and set and costume designs (5:28). Grade: film 3.5 stars; extras 2 stars

Rating guide: 5 stars = classic; 4 stars = excellent; 3 stars = good; 2 stars = fair; dog = skip it

Bridget Jones: Mad About the Boy (Universal, Blu-ray, R, 125 min.). The fourth film in the “Bridget Jones” franchise may not have the ending one was hoping for, but it brings back all the old faces, plus two new notable ones, making for a welcome return. It has been nine years since “Bridget Jones’s Baby.” Now Bridget has two children – Mila Jankovic as Mabel Darcy and Casper Knopf as Billy Darcy – to take care of and she has grown tired of the routine in her life. So, she decides to put herself out in the dating world again.

Topping the cast, of course, is Renée Zellweger (also “Chicago,” “Jerry Maguire”) as widow Bridget, stuck in a rut, with no job and most of her social interaction consisting of brief discussions with other parents as she drops her children off at school, although the most interesting such conversations are with Bill’s science teacher, Mr. Walliker (Chiwetel Ejiofor of “12 Years a Slave”). It has been four years since Bridget lost her husband (Colin Firth as Mark Darcy, who does make a sweet cameo appearance here).

In the film, Bridget finds employment on a popular talk show, where her skills as a television producer are a perfect match. Romantically, she meets 29-year-old Roxster (Leo Woodall of TV’s “The White Lotus,” “One Day”), who gallantly rescue Bridget and her two children from a tree and then professes romantic interest in her despite their age difference. Roxster’s connection both delights and frightens Bridget, as their quick turn to sexual experiences rocks her world.

The film, directed by Michael Morris (TV’s “Better Call Saul,” “13 Reasons Why”), deals with Bridget’s frustrations of dating and love. However, fans of the series will enjoy the reunion time with the people in Bridget’s life, including Jim Broadbent as Colin Jones, Gemma Jones as Pamela Jones, Sally Phillips as Shazzer, Emma Thompson as Dr. Rawlings and, especially, Hugh Grant as Daniel Cleaver, who remains a swinging single man, launching quips in all directions, and still a pal to Bridget, as he is willing to sit with her children while she tries to get her groove back.

The film also has the usual silliness. One time Bridget uses a black-market lip serum that briefly contorts her face.

Extras include four deleted scenes (6:31), including a long drunken meeting with Nicolette (Leila Farzad); a look at the series’ 25-year history with book author and co-scriptwriter Helen Fielding (4:52); a making-of feature that shows how some of the costumes from the previous films were aged and reused (8:19); and a look at Bridget’s men in the film (5:06). Grade: film 3.5 stars; extras 2 stars

Oliver! (Great Britain, 1968, Sony Pictures, 4K Ultra HD, G, 153 min.). Director Carol Reed’s version of Lionel Bart’s musical, based on Charles Dickens’ “Oliver Twist,” won six Academy Awards, including Best Picture, Best Director and Best Score. A well-deserved Honorary Oscar went to choreographer Onna White.

After being sold by the Workhouse Home to mortician Sowerberry (Leonard Rossiter) because he asked for more food, young orphan Oliver Twist (Mark Lester, later of “Melody,” “Crossed Swords”) runs away and meets The Artful Dodger (Jack Wild of “Melody,” TV’s “H.R. Pufnstuf”), who introduces him to a group of 20 boys trained to be pickpockets by their elderly mentor Fagin (Ron Moody, also of “The Twelve Chairs,” “The Mouse on the Moon”) in 1830s London. Moody earned an Oscar nomination for the role.

Through Fagin, Oliver meets Nancy (Shani Wallis of “Once Upon a Mattress,” “The Great Mouse Detective”), the singing girlfriend of adult thief Bill Sikes (Oliver Reed of “Gladiator,” “Women in Love,” “The Three Musketeers”), a menacing figure who takes Oliver prisoner at one point to use him in a robbery that goes bad.

Among the many famous songs are “Food, Glorious Food,” sung by the 70 Workhouse boys; “Where Is Love,” sung by Oliver; “Consider Yourself,” sung by The Artful Dodger, Oliver and the chorus; and “As Long as He Needs Me,” sung by Nancy. There are many street scenes with workers of various types singing and dancing. One such is “Who Will Buy?” which includes a knife-sharpener. (That brought back memories of my own childhood, as a knife-sharpener used to come to the Brighton, Mass. federal housing project where I lived in the 1950s.) During Nancy’s visit to Fagin’s lair, the pickpocket boys act like a carriage in a clever dance number.

Extras include audio commentary by film historian Steven C. Smith; Wild’s screen test (1:26); a behind-the-scenes featurette (7:37); “Meeting Oliver” (14:45); “Meeting Fagin” (13:24); locations of the film (4:37); sing-alongs (8 songs; 36;09); and dance-alongs (3 songs; 12:53). Grade: film 4.5 stars; extras 3.5 stars

Rhapsody in Blue (The Story of George Gershwin) (1945, Warner Archive Collection, Blu-ray, NR, 161 min.). This restored edition of the film, from scans of nitrate materials, adds some 12 minutes of footage never before seen by the general public, as well as the 10:15 overture of Gershwin melodies that only accompanied the film during its New York and Hollywood premiere engagements. It also includes the intermission and entr'acte music.

Robert Alda (“Cinderella Jones,” “The Beast with Five Fingers”) plays George Gershwin, while his brother, lyricist Ira Gershwin, is played by Herbert Rudley (“Brewster’s Millions,” “The Court Jester”). The two main women is his life are singer/Broadway performer Julie Adams (Joan Leslie of “Sergeant York,” “Yankee Doodle Dandy”), who he admits too late that he loves, and painter Christine Gilbert (Alexis Smith of “Conflict,” “The Age of Innocence”), who he meets in Paris, but who later turns down his marriage proposal in New York.

Playing themselves in the film are Al Jolson, who adds Gershwin’s “Swanee” to his show “Sinbad”; Oscar Levant, as a friend and music co-writer; band leader Paul Whiteman; and George White, creator of the Broadway “Scandal” shows. Another important role is played by Albert Bassermann as Professor Franck, the teacher who pushes Gershwin towards European classical music.

The fictionalized film follows Gershwin’s rise from a song plugger for a Manhattan music publishing firm, where he could not get his own songs published but did meet Julie Adams, starting their long friendship, to his having hit and after hit in Broadway shows, including White’s annual “Scandals,” for which Gershwin wrote the music beginning in 1920. At the urging of Franck, Gershwin writes “Rhapsody in Blue,” which debuts at Aeolian Hall in 1924 under the baton of bandleader Whiteman.

When Franck dies, Gershwin goes to Paris and meets Gilbert. A later return to Paris leads to Gershwin composing the ballet, “An American in Paris.” Gershwin died of a brain tumor at age 38.

The sole extra is the ability to go directly to any of 27 musical numbers. Grade: film 3.5 stars

Mystery Street (1950, Warner Archive Collection, Blu-ray, NR, 93 min.). The fun of this film is seeing Boston and Cambridge as they were in 1950, when I lived in the area as a child. The smart of this police procedural film is how it uses crime scene investigative techniques long before they became standard, especially on television.

Ricardo Montalban (“Star Trek II: The Wrath of Khan,” two “Planet of the Apes” films) stars as police Lt. Peter Moralas, investigating the death of Vivian Heldon (Jan Sterling of “Johnny Belinda,” “Ace in the Hole”), a young woman who was having an affair with a wealthy yacht designer, located in Barnstable on Cape Cod. Her only-bones body is discovered by an ornithologist in the dunes.

Prior to her death, we see Heldon pick up Henry Shanway (Marshall Thompson of “Battleground,” “It! The Terror from Beyond Space”) at a Boston bar, mostly so he can drive her to Barnstable as yacht designer James Joshua Harkley (Edmon Ryan of “Topaz,” “Tora! Tora! Tora!”) refuses to come and get her. After they stop at a restaurant in Barnstable, she steals Shanway’s car. Shanway later reports the car stolen, but says it was taken in Boston, as he does not want his wife (Sally Forrest of “While the City Sleeps” as Grace Shanway) to know anything about his interaction with Heldon, but that only makes him look more suspicious to Moralas, after he becomes the main suspect.

During his investigation, Moralas teams up with Harvard University Dept. of Legal Medicine’s Dr. McAdoo (Bruce Bennett of “Mildred Pierce,” “Sahara,” “The Treasure of the Sierra Madre”), who uses CSI techniques to prove Heldon was murdered and how it probably happened. There are several scenes at Harvard University sites in both Cambridge and Boston.

Practically stealing the film is Elsa Lanchester (“Bride of Frankenstein,” “Witness for the Prosecution”) as Heldon’s Beacon Hill landlady, Mrs. Smerrling. A penny-pincher, Smerrling gathers enough information to try and blackmail Harkley, and even steals the murder weapon.

The film, directed by John Sturges (“The Great Escape,” “The Magnificent Seven,” “Bad Day at Black Rock”), has an exciting final chase through a train yard. Extras include audio commentary by film historian Alain Silver and Elizabeth Ward; a short making-of that includes cinematographer John Alton (“Father of the Bride,” “An American in Paris,” “The Brothers Karamazov”) and the film’s CSI aspects (4:54); and two Tom and Jerry cartoons, the cute “Little Quacker,” with Tom stealing a duck egg that hatches (7:11) and the musical “Tom and Jerry at the Hollywood Bowl,” with Tom conducting an all-cat orchestra, until Jerry takes over (7:26). Grade: film 4 stars; extras 3 stars

Three Comrades (1938, Warner Archive Collection, Blu-ray, NR, 98 min.). In this weeper, three German soldiers in 1918 open a repair shop together. The three are Erich Lohkamp (Robert Taylor of “Quo Vadis,” “Camille”), Gottfried Lenz (Robert Young of “Northwest Passage,” TV’s “Marcus Welby, M.D.”) and Otto Koster (Franchot Tone of “Mutiny on the Bounty,” “Dangerous”). All three fall for the charms of Patricia Hollmann (Margaret Sullavan of “The Shop Around the Corner,” “The Shopworn Angel”), not knowing she has tuberculosis.

The film covers several years and includes Lenz falling in with a forbidden anti-nationalist group. It is an adaptation of Erich Maria Remarque’s novel, with F. Scott Fitzgerald’s (author of “Tender Is the Night,” “The Great Gatsby”) sole screenwriting credit. The film was directed by Frank Borzage (“No Greater Glory”) and Sullavan earned an Oscar nomination.

Extras include the short “The Face behind the Mask” (10:46), a historical mystery about French King Louis XIV’s prisoner in the iron mask; and the Robert Benchley short, “How to Raise a Baby” (3:02). Grade: film 3 stars; extras 2 stars
