PHOENIXVILLE — Celebrating its 25th year, Blobfest has become a landmark event in the Phoenixville community and the greater Philadelphia region every summer. For more than two decades, the weekend-long festival highlights the iconic 1958 cult movie, “The Blob” which was filmed locally in Chester County, including Phoenixville. Thousands of people attend the festival each year paying homage to an early sci-fi classic starring screen legend Steve McQueen and his quest to save an entire town from the now iconic gelatinous movie monster.

“Blobfest is Phoenixville’s claim to fame in classic Hollywood and the festival makes for a fun, off-beat way to celebrate that,” said Drew Boardman, event director at the Colonial Theatre. “It’s great for people from all walks of life, and a cool history for people to share with generations to come. A mix of the off-beat and generational aspects has made for a festival that endures.

” Festivities began on Friday night with the crowd-favorite “Run-Out” event. Hundreds of fans reenacted the most iconic scene from the film, as they ran screaming out the front doors of the Colonial Theatre onto Bridge Street. Afterward, the annual Blob Ball was held in the theater’s lobby, hosted by Lulu’s Boutique and Gifterie.

People danced the night away dressed in colorful 1950s outfits and an array of costumes. “With the big anniversary, we’re going full Blob! We have screenings all day Saturday of the film, a late-night screening .
