As Zachary's violent personality begins to take over the child, the Duncans must find a way to save their son and themselves from the doctor's dark experiment. Cast and Production Key Cast: Robert De Niro as Dr. Richard Wells Greg Kinnear as Paul Duncan Rebecca Romijn as Jessie Duncan Cameron Bright as Adam Duncan Director: Nick Hamm Screenplay: Mark Bomback

The film transitions from a drama about grief into a supernatural horror after the cloned "Adam II" reaches his eighth birthday—the same age the original Adam died.

Adam begins experiencing terrifying night terrors and vivid visions of a boy named Zachary.

It is eventually discovered that Dr. Wells used the DNA of his own deceased son, Zachary—who died in a fire after killing his mother—to supplement Adam's cloning process.

The film was a modest financial success, grossing over $30 million despite receiving largely negative reviews from critics. Notable Features & Trivia Godsend (2004)
