Actor SHIA LaBEOUF sustained a painful groin injury on the set of INDIANA JONES AND THE KINGDOM OF THE CRYSTAL SKULL, when a sword fight with Cate Blanchett went drastically wrong.
The Australian actress plays a villain in the forthcoming adventure sequel alongside LaBeouf and the pair's characters end up slugging it out in a fencing match.
And the 21-year-old Transformers star insists he had never felt "real pain" until he was injured by Blanchett in the action sequence.
He says, "If you ever want to feel real pain, try a sword fight with Cate Blanchett. It worked for me.
"I sustained my biggest ever injury on this shoot when fencing with Cate. I slipped and tore some muscles in my hip. I it was extremely painful to walk and the pain started spreading to my groin.
"Now you don't want your groin to be non-operational at any time, but especially when you've got an Indiana Jones film to complete."
