'Blobfest' turns 55 in Chester County, Pa.

PHOENIXVILLE, Pa. - July 13, 2012

It was an iconic moment in movie history. 55 years later, people are still running.

It's indescribable! Indestructible!

"You cannot kill the Blob. You can only stop it. And you stop it by freezing it in its tracks," said Wes Shank.

Shank owns a piece of movie history: the monster from the iconic 1958 horror film 'The Blob.'

"It's industrial silicone made by Union Carbide at the time," said Shank.

This weekend hundreds of people will come from all over the world to the Colonial Theater in Phoenixville, where parts of 'The Blob' were filmed.

"When they show the film and you're watching it and that scene comes on, everyone just goes crazy," said Sandy Ashton of Wynnfield Park, N.J.. "And it's just really exciting to be there."

Charlie Philllips dresses up in his alien costume every year.

"Somebody always helps me get through the door, because last time I almost lost my head," he said.

Action News got an exclusive up-close look at the movie monster Friday night.

It has a distinct smell. It's sticky. And the Blob still moves, even today.

"What's so super scary is this stuff is going to outlive me," said Shank.

And that is enough to send people running, after all these years.

If you want to get in on the Blob Fest fun, there is a street festival right in front of the theater Saturday.

They are showing the movie at 8:00 p.m.
