In the 90s, cult-TV show Mystery Science Theater 3000 turned trashing a flick into an art form. Despite the shows cancellation, former host Michael J. Nelson just cant leave the bad movies of the world alone. Nelson is the driving force behind Rifftrax.com, a variation on MST3Ks shtick, only now you download the audio commentary tracks and synch them yourself. Rifftrax has done well enough that theyre taking the show on the road sort of. Local theaters host a live airing of Rifftrax: Ed Woods Plan 9 From Outer Space (pictured) from the Belcourt Theater in Nashville, Tenn. Joining Mike for the cutting commentary are MST3K staples Kevin Murphy and Bill Corbett. Visit fathomevents.com for ticket prices and info. The show screens at two local theaters, including: Citrus Stadium Park Mall 20, 7999 Citrus Park Town Center Mall, Tampa; and Regency 20, 2496 Brandon Blvd., Brandon. Thu., Aug. 20, 8 p.m.
