Well-timed to open soon after genome pioneer Craig Venter's announcement of a self-replicating cell, here's a halfway serious science-fiction movie about two researchers who slip some human DNA into a cloning experiment, and end up with a unexpected outcome or a child or a monster, take your pick. The script blends human psychology with scientific speculation and has genuine interest until it goes on autopilot with one of the chase scenes Hollywood now permits few films to end without. In the laboratory of a genetic science corporation, we meet Clive and Elsa (Adrien Brody and Sarah Polley), partners at work and in romance, who are trying to create a hybrid animal gene that would, I dunno, maybe provide protein while sidestepping the nuisance of having it be an animal first.
