Scorpius Gigantus is a 2006 American science-fiction film from producer Roger Corman directed by Tommy Withrow. It was a remake of Carnosaur 3.

Reel Film called it "an effort that's pretty much a wash on every level, and it hardly seems likely that Roger Corman himself would be able to muster up a convincing recommendation."

Dread Central said the film "doesn’t bring anything new to the formula, nor does it even aspire to do so. That would be acceptable if it at least did a good job being a retread. It doesn’t."
