"Deadheads" mark your calendars.  The late-'70s rockumentary "The Grateful Dead Movie" is returning to the big screen for one-night-only next month.  The Oxford Seven Cinema in Oxford is one of  540 theaters across the U.S. that will screen the movie on April 20th.  The feature-length film was directed by Leon Gast and the band's frontman Jerry Garcia.  It focuses on the Dead's 1974 concerts in San Francisco, California -- while also taking a look at the expansion of the "Deadhead" culture.

The April screening will mark the first time that "The Grateful Dead Movie" has returned to big screens since its 1977 theatrical run.

That's right the date to see "The Grateful Dead" at the Oxford 7 Cinema is 4/20.  Cool.
