This week’s DVD releases each seem to have an clear affiliation with one of the famous triumvirate of naughties. But behind a movie’s obvious basis in one vice is usually a subtle, ephemeral tribute to one of the others…

Harold and Kumar Escape from Guantanamo Bay: It’s safe to say Drugs are the overriding theme in a film when it’s classified as a “stoner comedy,” but for Sex, you can’t discount the power of Neil Patrick “I Wanna Sex You Up” Harris. Also, this movie has a lot of vaginas.

Never Back Down: Don’t lie to yourself, this is total soft-core porn. It’s all about virile young would-be competitive reality cast-offs sweating, stripping down half naked, and getting in street fights that somehow never end with someone getting kicked in the junk — let alone shot in the face. However, I have to admit that underground kickboxing clubs coached by built African guys are, in essence, pretty Rock and Roll.

Shine a Light: A documentary about perhaps the most definitive rock and roll band in history is pretty, well, Rock and Roll. But it doesn’t get more Drugs than those bearded lost weekends Marty spent with the Stones back in the ’70s, lost in a haze of 8-balls and aviator sunglasses.*

Also on DVD this week: Doomsday, Surfwise, and the Band’s Visit.
