The General
(Kino International, $29.95)
Buster Keaton’s uncanny sense of “visual humor makes The General such a joy,” said The Dallas Morning News. His 1926 film about a Confederate railroad engineer who trails a train commandeered by Yankee spies features “one daring and inventive gag after another.”

(Paramount, $29.99)
Jack Black “gives voice, and emotion,” to a “roly-poly panda” who dreams of becoming a martial arts master, said The Philadelphia Inquirer. Amusing extras include instructional videos that teach kids how to do everything from use chopsticks to draw the film’s characters.

Christmas on Mars: A Fantastical Film Freakout Featuring the Flaming Lips
(Warner Bros., $24.99)
