Scott “Biff” Grant of The Monolith Monsters yachts through a glitter cloud, his wife (of I Was a Male War Bride) unaffected since she was in the cabin. “People actually decrease in height during the day,” says a doctor trying to comfort him. But it’s no use, doc, Biff is definitely getting smaller, and being a real pain in the ass about it. He goes out on the town and meets circus midget April Kent, but that doesn’t help either. Finally he’s small enough to be chased around by the family cat – he escapes into the cellar, but his brother Charlie arrives, and refusing to look in the cellar declares his brother definitely dead then wanders off with the hot wife. Meanwhile, Biff makes a grappling hook (this is exactly what I used to assume I’d do in any desperate situation) to defeat a spider, after which he reaches transcendence as he vanishes into atoms.

Per Criterion, Joe Dante (of course!) loved this movie, and cast the doctor in Innerspace… the same cat who tried to kill Biff later starred in Breakfast at Tiffany’s… I should really watch the remake with Lily Tomlin and Charles Grodin.
