Room 237
(MPI Home Video, $28)
This “enormously entertaining” documentary about the hidden messages some fans see in The Shining functions as “a celebration of impassioned filmgoing,” said The Wall Street Journal. Was Stanley Kubrick’s 1980 film a Holocaust allegory? Proof that the moon landings were faked? You decide.

Call Me Kuchu
(Docurama, $30)
Yes, there are still places where you can go to prison just for knowing someone who’s homosexual, said NPR.org. This “horrific and uplifting” documentary is, in part, a profile of the first openly gay man in Uganda and the brave activists he led. “It becomes a privilege to know them all.”

(Disney, $30)
