Get Spooked With The Ultimate Cult Classic And Free HBO. For Free.

From: Queerty

It’s just a jump to the left, and then a free midnight streaming of The Rocky Horror Picture Show to the right.

So if your version of Halloween mayhem is locking the door, lowering the blinds and pretending not to be home, now you can pass the time with a screening of the best damn thing to come out of 1975 (or was that Queen’s A Night At The Opera?) — Tim Curry slaying it as Dr. Frank-N-Furter, Susan Sarandon discovering her bad side as Janet (dammit) and Peter Hinwood’s perfect gold booty shorts.

The event also lines up with the films 40th anniversary, and fans are encouraged to dress up as their favorite characters and to think creatively about how they can translate the film’s iconic participation cues for social media.

So bust out the rice and prepare to yell at your TV screen.

Fans who want to participate can tag #RHPS40 on Twitter Halloween night and the @HBONOW handle will retweet the best posts throughout the night.
