Blobfest in Phoenixville
Blobfest is a three-day summer festival in downtown Phoenixville, Pennsylvania, celebrating the 1958 cult horror film The Blob, portions of which were filmed at the borough's Colonial Theatre. Started in 2000 by the theatre, the event mixes horror-movie screenings with a street fair, costume and film contests, and a signature reenactment of the film's famous theater-emptying scene.
Its movie-location identity and reenactment make it an excellent weird film row.
