Lucas wanted to cast a relatively unknown actor, who would commit to a trilogy of films, to play Indiana Jones. Those considered for the role included: Bill Murray, Nick Nolte, Steve Martin, Chevy Chase, Tim Matheson, Nick Mancuso, Peter Coyote, Jack Nicholson, Jeff Bridges, and John Shea. Casting director Mike Fenton favored Bridges but Lucas' wife and frequent collaborator Marcia Lucas preferred Tom Selleck. Selleck was contractually obligated to filming the television series "Magnum, P.I." if it were to be made into a full series. Lucas and Spielberg asked the show's studio, CBS, to release him early 10 days early from his contract. Realizing Selleck was in demand, CBS greenlit "Magnum P.I.", forcing him to drop out and leaving the production with no lead actor only weeks before filming. Ironically, the actors' strike of 1980 put the show on hiatus for three months, which would have allowed Selleck to star as Jones.
