Friday's late-night showcase for low-budget exploitation flicks gets some fresh meat from Turner Classic Movies with the delirious blaxploitation musical biker flick Darktown Strutters (Friday night at 2 a.m. ET, TCM).

I've never seen it, but Cinebeats has, and the rundown here has me drooling with antici-pation: Stylish Watts women take on the KKK and a clone king, while looking entirely too fab riding their multicolor machines. Rev up the DVR for a movie that "must be seen to be believed." (See some here.)

Following Darktown Strutters on the bill late Dec. 18/early Dec. 19 is Thank God It's Friday (3:45 a.m. ET, TCM), disco diva Donna Summer's 1978 showcase, co-starring such big names as Valerie Landsburg and Terri Nunn. (Look close for early work from Jeff Goldblum and Debra Winger, who I'm sure would rather not be reminded.)

TCM Underground takes a hiatus next week (pre-empted for a Sherlock Holmes festival), but January promises cheap thrills like the 1969 LSD saga The Big Cube (with Lana Turner!) and Jerzy Skolimowski's '70s double feature Deep End and The Shout. Also expect witchcraft, Satanism, female crime gangs and Blue Velvet. Be there or be square.
