Tom Selleck says Steven Spielberg originally wanted him for 'Indiana Jones' before casting Harrison Ford

Tom Selleck is doing a lot of reflecting ahead of the release of his book, "You Never Know: A Memoir."

Before breaking into the business, Selleck admittedly struggled to find permanency in Hollywood, having taped 6 pilots before finally landing one that stuck: "Magnum P.I." 

When good fortune struck for Selleck, it seemed to come tenfold. After shooting "Magnum," Selleck was offered the lead role in the 1981 picture, "Indiana Jones: Raiders of the Lost Ark," by its famed director, Steven Spielberg, himself.
