Get ready to do the Time Warp again… and again… and again… this Halloween when Fox Movie Channel does a Rocky Horror Picture Show marathon where they’ll be showing the 1975 cult film continuously for 24 hours!!!

But before the October 31st marathon, Fox Movie Channel will air an exclusive extended version of the movie on Tuesday, October 26 immediately following the Halloween-themed episode of Glee called “The Rocky Horror Glee Show,” which begins at 8:00-9:00 PM ET/PT on FOX. In the episode, the gang performs tunes from the long-running horror-scifi musical, which celebrates its 35th anniversary this year.

If you want to see the film again before the Glee episode, The Rocky Horror Picture Show 35th Anniversary Edition Blu-ray comes out on October 19, 2010. This is one of my favorite movies ever, so I highly recommend it and can’t wait to see how the Glee gang performs the awesome tunes from the film.
