Now and Again (1999)

When Michael Wiseman is killed in a tragic subway accident, the U.S. government covertly makes him an offer he can't refuse; they "keep his brain alive" and place it into a new, genetically bio-engineered body. The doctor in charge of the experiment has grand plans for him, but all Michael wants is to get back to his grieving wife and daughter. For security reasons, the government forbids such contact... not that Michael is going to let that stop him.
