The Fortune Cookie (alternative UK title: Meet Whiplash Willie) is a 1966 film starring Walter Matthau and Jack Lemmon in their first on screen collaboration, and directed by Billy Wilder.
CBS cameraman Henry Hinkle (Jack Lemmon) gets injured when football player Luther "Boom Boom" Jackson (Ron Rich) runs into him while he is covering a Browns game at Cleveland Stadium. Hinkle is visited in the hospital by his conniving lawyer brother-in-law "Whiplash Willie" Gingrich (Walter Matthau), who convinces him to pretend that his legs have been paralyzed. This way, they can receive a huge indemnity from the insurance company. Of course, the insurance company suspects that the paralysis is a fake one, and so a cat-and-mouse game begins. Jackson turns out to be a nice guy. He takes very good care of Hinkle, who begins having second thoughts as he witnesses guilt taking its toll on Jackson.
