In the vein of Leatherface’s chainsaw swinging dance at the end of The Texas Chainsaw Massacre being compared to Julie Andrews’ iconic spinning in the alps of The Sound of Music, Twitter is seeing what other musicals can get horrified.

Just in time for the spooky season, Saturday’s trending #HalloweenMusicals reveals the creative side of Twitter leading up to All Hallows’ Eve. Horror-centric musicals like The Rocky Horror Picture Show, Sweeney Todd, Little Shop of Horrors, and Carrie prove that the joy of music can be found in even the darkest of settings, but what about adding spider webs and black cats to the upbeat works?

Westside Story involves street gangs going head-to-head in a Romeo and Juliet type situation, and changing the name to Westside Gory only accents what’s already there. The memorable and upbeat score of Singin’ in the Rain gets mixed with John Carpenter’s ferocious, snow-set The Thing in another mash-up. Of course, it wouldn’t be a proper Halloween and film crossover without Broadway star Bette Midler’s iconic performance in Hocus Pocus.

Check out below some of the best crossovers that will put a spell on you.
