Timebomb is a 1991 American science-fiction action film written and directed by Avi Nesher and starring Michael Biehn, Patsy Kensit, and Richard Jordan.
Mild-mannered watchmaker Eddy Kay (Michael Biehn) runs into a burning building to save a trapped woman and is featured in the news as a result.
A game of cat and mouse begins as Eddy, with the help of psychiatrist Dr. Anna Nolmar (Patsy Kensit), tries to discover his past and why they want him dead.
Using various sensory deprivation and brainwashing techniques, the assassins could be sent to infiltrate other organizations and facilities undetected and carry out programmed missions.
[1] Producers originally wanted Jean-Claude Van Damme or Chuck Norris to play Kay, but Nesher saw Biehn as perfect for the role due to his performance in The Abyss.
