Trivia

Chuck Russell and Frank Darabont didn't have a lot of rules for the Blob, but they agreed to the general concept of the creature basically being an inside-out stomach, meaning the acid is burning, melting, and devouring almost everything it touches: "It's a monster in its simplest form. There must be something about this thing that can slide under your door or squeeze through an air vent, or quietly dissolve somebody in the next room, that's very elemental. It just makes monstery sense. It's a fear of the worst death: being eaten."

Chuck Russell is a big advocate of storyboarding shots in advance. "When I first came to California, I gate-crashed Universal when Hitchcock was still working, went into Hitchcock's office, said I'm here to see Mr. Hitchcock, and I could see him working with a storyboard artist."

Donovan Leitch Jr. (Paul) took Shawnee Smith (Meg) to his senior prom at Hollywood High. He wrote her a thank you note afterward, which she kept for years. They later appeared together in this film.

Of the film's reported $15 million budget, $5 million went toward visual effects, although director Chuck Russell claims that both numbers are highly exaggerated, and the total budget was closer to just under $10 million.

Chad McQueen was offered the part of Brian Flagg but turned it down. He did so due to disliking the script, and to having a strict personal policy of never performing in any production based on, or inspired by, the work of his actor-father Steve McQueen, who was in the original The Blob (1958).
