When Pitt started to get regular work, he was inarguably handsome, but his leading-man potential was unclear. Two of his best-received performances were as slimebag criminal boyfriends, in the TV movie Too Young to Die? (1990) and the theatrical release Kalifornia (1993). Both were made with wild-child Lewis—literally a child, as she was 16 when they started dating.
Brad ended up going down the path of stardom suggested by A River Runs Through It, but you have to wonder who he'd be if he had stayed with Lewis. Perhaps the Mickey Rourke of his generation? Alas! We'll never know.
