New this week on DVD and Blu-ray:
''Rock of Ages'' - The jukebox musical still running on Broadway makes a sloppy transition to the screen. It serves up the sounds, the hair and the clothes of the '80s and camps it up with a dose of theatrical excess, but the direction by Adam Shankman (who did much better with ''Hairspray'') verges on incoherent. The tone shifts from winking to self-mocking to earnest, frequently within the same scene.
Tom Cruise brings an admirable intensity to rock god Stacee Jaxx, but the performance feels as if it belongs in a different movie. Also, he's a supporting player (along with Alec Baldwin, Russell Brand and Paul Giamatti), and the leads (Julianne Hough and Diego Boleta) couldn't be more bland.
The movie is being released in an extended edition featuring scenes not included in the theatrical release. The disc also comes with the multi-part featurette ''Defining a Decade'' and selected songs. (Warner Home Video, $29.98 DVD, $35.99 Blu-ray)
''Prometheus'' - In this kind-of prequel to ''Alien,'' archeologists lead a mission, funded by the Weyland Corporation, to a distant star that may offers clues to the origin of mankind. Noomi Rapace, Logan Marshall-Green, Charlize Theron, Michael Fassbender and Guy Pearce star in a film directed by original ''Alien'' director Ridley Scott.
Extras include two commentary tracks, one with Ridley Scott and a one with writer Jon Spaihts and write / executive producer Damon Lindelof; deleted / alternate scenes including an alternate opening and ending; screen tests; and multiple featurettes.

''Magical Mystery Tour'' - The Beatles' third film project, remembered more fondly for some of its songs (''Fool on the Hill,'' ''I Am the Walrus'' and the title track) than for its cinematic content, makes its Blu-ray debut.
