This week’s MSN DVD column takes a look at three new releases targeted at teens — Joseph Kahn’s “Detention”, about which more this week, and also Noel Clarke’s “4.3.2.1” and Liza Azuelos’ “LOL”. Not the most fertile of genres, the teenpic, but “Detention”, at least, is trying to do something new.

More importantly, Chris Marker has died — and on his 91st birthday, which seems kind of uncouth. Celebrate his memory by watching “La Jetee” right here, if you’re so inclined, and then spin up “The Beaches of Agnes” to see what I believe is his final on-screen appearance, in a manner of speaking.
