Every year, the Colonial Theatre in Phoenixville, Pennsylvania holds Blobfest. The Blob (1958) was made in and around Phoenixville. The scene in the film where they run terrified out of the theater was filmed at the Colonial Theater.
The 14th Annual Blobfest (July 12th-14th, 2013) will focus on bugs this year. Friday night Colonial will be showing The Blob, after which the audience will run out screaming in a re-enactment of the movie. This event sells out almost immediately every year so buy tickets early. The Runout can be watched from outside at 9 p.m. Keith Almoney, who played little Danny in the film, will be on hand for autographs.
Saturday afternoon will be a double feature of The Blob and Them!. All day on Saturday, Phoenixville will have a street fair, including a fire extinguisher parade and costume contest. Saturday night will be The Blob and Tarantula. Sunday afternoon will be The Blob and The Deadly Mantis.
