OAKS, Pa. — Monster-Mania Convention marks its 65th show this weekend, rolling into the Greater Philadelphia Expo Center with a familiar chill that’s kept it a staple for horror devotees for more than two decades.
The Oaks gathering, which runs from Nov. 21-Nov. 23, 2025, promises an extra shiver: an X-Files reunion anchoring a weekend packed with genre icons, monsters, and a heavy dose of nostalgia.
For founder Dave Hagan, the milestone weekend is the latest chapter in what began as a simple “what if” conversation more than 20 years ago.
Hagan and his family were vendors on the Philadelphia/New Jersey convention circuit when a drive home from a Pittsburgh show with his oldest son sparked an idea to create a horror convention. They wanted it to feel different - more like a friends and family gathering, more welcoming, and lots of fun.
“We do the conventions in honor of my dad,” Hagan said. “My dad used to take me to horror movies all the time when I was a kid.”
The first Monster-Mania landed at the former Clarion Hotel in Cherry Hill, N.J., in 2003. The hotel offered a date that coincided with the weekend of his father’s birthday, so Hagan booked it. The event drew enough fans and energy to quickly outgrow the venue.
For 22 of its 23 years, the convention has planted roots at Doubletree by Hilton Cherry Hill Philadelphia, while expanding to additional shows in Baltimore, Md., and Oaks.
“It is nonstop,” Hagan said of planning the conventions, which run four times a year. “It’s something that you have to love to do.”
He said organizing Monster-Mania doesn’t end when he goes to bed. He even dreams of various aspects of its planning.
“I literally wake up from sleeping and have ideas,” he said.
One of Hagan’s goals has always been to recreate the experience of his own early movie fandom. He was the first among his friends to own a VHS player and would host weekend movie nights — the vibe he still wants the convention to capture, he said.
“I wanted the convention to be like a larger house party,” he said.
He also wanted the convention to appeal to guests with varying interests, including newer horror movies, retro monsters, and some pop culture.
Monster-Mania’s guest lists have long reflected that mix. Hagan’s years as a vendor helped him connect with actors like Ben Chapman, who played the Creature in Creature From the Black Lagoon in land scenes and helped him recruit early celebrity guests.
Chapman appeared at the first Monster-Mania alongside fellow Creature From the Black Lagoon actress Julie Adams, actresses from classic Hammer Films, as well as Doug Bradley, famed for playing Pinhead in Hellraiser. Bradley remains a frequent guest.
Robert Englund, most known for his role as horror icon Freddy Krueger, appeared at Monster-Mania’s second show, a booking that left the Hagans a bit starstruck.
“Wow, we've got a guy that we went to the movies to see,” Hagan recalled.
Englund also helped validate the young convention. Hagan recalled running into him near the end of the weekend, and he complimented the show.
“That, to me, meant the world,” Hagan said.
The 65th edition continues the tradition of mixing marquee names with fan-favorite horror stars. The X-Files reunion will feature six cast members - Gillian Anderson, Robert Patrick, Mitch Pileggi, William B. Davis, Annabeth Gish, and Laurie Holden.
Other guests include Jeremy Davies and Madeleine McGraw from The Black Phone films, Ralph Macchio and William Zabka from Cobra Kai, Juliette Lewis, C. Thomas Howell, Michael Rooker, Linda Blair, Jackie Earle Haley, and Vincent D'Onofrio.
This weekend’s Oaks show features roughly 400 booths and tables — about 100 more than the convention’s hotel-based events — offering everything from classic monster memorabilia to modern horror art and broader pop-culture collectibles.
Through it all, Hagan said the mission remains the same: create a place where fans feel at home. He described horror fans as loyal, knowledgeable about the genre they love, appreciative and respectful.
“Horror fans are a great group of people,” Hagan said. “I think they're unlike any kind of movie fan. We just want you to come out and have a good time. ”
