The Smashing Machine (out Oct 2) may earn Dwayne Johnson a first Oscar nomination in that he's doing something different, he’s playing a real-life person, and he’s wearing a lot of prosthetics. That said, this biopic of wrestling pioneer Mark Kerr never gets out of first gear. There's a bunch of interesting subplots but, in jumping all over the place, the film struggles to finish any of them. Grade: B-.
