Jason Statham
Statham was actually the farthest thing from an actor that anyone on this list has been so far. He was a competitive amateur high diver that sold jewelry out on the streets of London to make ends meet. A talent scout just so happened to be marching past Statham one day when he was selling some watches, and he offered Statham an opportunity to come audition to play Guy Ritchie.
From Deep Dives to Big Checks
Statham was offered a small role in Lock, Stock, and Two Smoking Barrels. Evidently, The director of the movie was looking for a fit guy to, well, impersonate a street watch salesman. Statham wasn't going anywhere with his diving career, so he decided to take the role. He then went on to become one of Hollywood's most iconic actors.
