Cavegirl (1985)

Cavegirl is the kind of cheerfully shameless 1980s time-travel comedy that knows exactly what it is: a goofy, low-stakes romp where a clueless teen stumbles into the Stone Age and promptly discovers that surviving prehistory is harder than flirting in high school. Its charm comes from the movie’s unpretentious, B-movie sincerity—Daniel Roebuck plays Rex with a sweet, fumbling energy, and the fish-out-of-water setup keeps the jokes moving even when the budget can’t. There’s mild nudity and a distinctly adolescent, sex-chasing premise, but it’s wrapped in a breezy, playful vibe with enough caveman-clan antics and light action to keep it from feeling like a one-note gag. If you’re in the mood for something polished or progressive, this isn’t it—but if you want a nostalgic, slightly naughty comedy that feels like a late-night cable discovery, Cavegirl delivers exactly that kind of goofy fun.

Cavegirl is clearly aiming for a goofy, low-stakes time-travel sex comedy with a caveman gimmick and a bit of “fish out of water” charm. The problem is the humor is thin and repetitive, the writing leans heavily on Rex’s one-track goal of getting Eba into bed, and the direction never finds a rhythm that turns the premise into actual laughs. If you’re sensitive to dated gender politics or you need clever jokes and a story that respects its characters, this will feel like a slog with occasional nudity doing most of the heavy lifting. Still, if you’re in the mood for a cheap, very 80s B-movie curiosity with mild skin, simple caveman-set antics, and low expectations, you might get a few half-smiles out of it.
