"Smart People" (R) Although smarter-than-your-average Hollywood comedy, this tale of academia and dysfunction still works only fitfully, despite a top-notch cast that includes Dennis Quaid, Sarah Jessica Parker, Thomas Haden Church and Ellen Page. Quaid plays a curmudgeonly college professor who sustains a head injury that throws him together with a former student turned doctor (Parker), while he copes with his shady brother (Church) and ultraconservative daughter (Page). The DVD and Blu-ray disc (Disney, $30-$35) feature nine deleted scenes, interviews and commentary by director Noam Murro and screenwriter Mark Jude Poirier. There's also a segment on the film's premiere at the Sundance Film Festival.

"Brand Upon the Brain!" (not rated) Canadian cult filmmaker Guy Maddin presents another film either truly wondrous or just plain weird, depending on your tolerance for the visual and sonic magic he layers onto his dense storytelling. His latest follows the adventures of a character named "Guy Maddin," who returns to his family homestead -- an island lighthouse -- to paint the structure by request of his aging mother. From there, the film flits backward to a wild rush of suppressed childhood memories involving his autocratic mom, his basement-inventor father, a murder mystery and strange experiments conducted on orphans. The DVD has narration tracks by Isabella Rossellini, Crispin Glover, Eli Wallach and others, including Maddin. There's also a deleted scene, a documentary on Maddin and two new short films he directed on the DVD (Criterion, $40).

"CJ7" (PG) Steven Chow, the martial-arts slapstick master of "Kung Fu Hustle," returns with a family-friendly tale utilizing his manic moves. Writer, director and star Chow plays a poor but loving blue-collar dad who stumbles on a strange orb that he presents as a gift to his young boy. The device turns out to be an alien entity that wreaks havoc and teaches some lessons to father and son. The DVD and Blu-ray release (Sony, $29-$39) includes behind-the-scenes segments, a game and commentary.
