We'll soon find out because a movie involving all that and more (depression, Mexico, murder) is actually being produced.
Al Ruddy, the 81-year-old Godfather and Million Dollar Baby filmmaker, will produce and Brad Furman (The Lincoln Lawyer) Ruddy bought the 1975 novel by the late N. Richard Nash who'd adapted it into the Cry Macho screenplay. In his heyday, Schwarzenegger was a $25M/25% first dollar gross mega-player -- and one deal even threw in his own giant jet. But only the rarest of the rare get those paydays these days. This pic calls for some acting chops for Arnold as a horse breeder who won the Kentucky Derby but whose wife and child get killed. He sinks into an alcoholic depression and winds up working for a hedge fund jerk who offers him a choice of getting fired or bringing back the rich guy's son living with the ex-wife in Mexico. Unexpected plot twists ensue, including an Arnold-and-kid road trip back home.
