One of the more popular features from Roger Corman's "B"-factory Concorde/New Horizons, Carnosaur perpetuates the grand Corman tradition of zeroing in on a big-budget Hollywood studio moneymaker, then dashing off a quick-and-dirty poor man's version before moss gets a chance to grow on the larger film's concept. This bargain-basement spin on Jurassic Park was actually based on a novel by John Brosnan (under the pseudonym Harry Adam Knight). It features Diane Ladd (whose daughter Laura Dern took the high road on Spielberg's film) as a kooky mad scientist whose experiments on human and dinosaur DNA result in dual disasters -- first, a rubbery midget Tyrannosaurus bred from dinosaur and chicken DNA (imagine the barbecue potential!) which escapes the lab and goes on the requisite bloody rampage; and second, a specially-engineered virus with the ability to replace human beings with dino-babies. Although this exploitation quickie doesn't waste too much time delivering the standard Corman cargo (blood and breasts), the mayhem is too often derailed by endless genetic techno-babble from Ladd, whose freaked-out performance is the film's sole plus. The downbeat ending is pure '80s, and paves the way for the inevitable sequels.
