    DVD releases: ‘Cosmos: A Spacetime Odyssey’

    Daniel Smith/FOX

    COSMOS: A SPACETIME ODYSSEY Astrophysicist Neil deGrasse Tyson updates Carl Sagan’s famed 1980 PBS science-documentary series. The 13 episodes were a surprise hit on Fox and the National Geographic Channel earlier this year. Extras: featurettes on “Cosmos” at the Library of Congress and Comic-Con, an interactive cosmic calendar. (20th Century Fox, $49.98; Blu-ray, $59.98)

    RAY DONOVAN: SEASON ONE Is this Showtime series a crime story? Character study? Family drama? Liev Schreiber plays a Boston guy who now works in LA as a “fixer” for a high-powered law firm. If that doesn’t keep Ray busy enough, his ex-con dad (Jon Voight) may or may not be informing on Ray’s activities to the FBI. (Showtime Entertainment, $55.98)

    DEVIL’S KNOT Atom Egoyan directs this 2013 retelling of the real-life story of three Arkansas teenagers falsely convicted of murder. Reese Witherspoon plays the mother of one of the teens. Colin Firth is the investigator who seeks justice. Also starring are Elias Koteas, Dane Dehaan, and Mireille Enos. Extras: making-of featurette, deleted scenes. (Image Entertainment, $29.96; Blu-ray, $34.97)


    OMAR Set in the moral quagmire of the occupied West Bank, Hany Abu-Assad’s film — a foreign language Oscar nominee this year — is told with a clarity that leaves you with fewer answers than before. Newcomer Adam Bakri plays the young hero, losing his political and personal innocence the hard way. (Adopt Films, $29.95; Blu-ray, $34.95)

    ALAN PARTRIDGE The fatuous local radio DJ created by comic actor Steve Coogan has been bouncing around England since 1991 in various formats, but this is the character’s first big-screen iteration. It’s refreshingly small, rude, and funny — the cinematic equivalent of Marmite, but try some, you might like it. Extras: behind-the-scenes featurette. (Magnolia, $26.98; Blu-ray, $29.98)

    VISITORS There are many arresting shots in Godrey Reggio’s New Age documentary, all of them long takes backed by a droning Philip Glass score. They show the beauty of the human face or the tragic grandeur of derelict buildings and amusement parks. Together they convey the same banal environmentalist message as in Reggio’s films “Koyaanisqatsi” and “Powaqqatsi.” Extras: making-of featurette, interviews with Reggio and Glass. (New Video Group, $28.95; Blu-ray, $34.95)
