Trivia, insights & behind the scenes
Roger Corman rushed this into production to beat The Lost World: Jurassic Park to video stores. It still lost.
The Carnosaur franchise—yes, franchise—actually started with a 1984 novel that predated Michael Crichton's book, making this technically not a ripoff but a parallel-universe embarrassment.
