Dominic Cooper almost blinded Luke Evans.
Filming 'Dracula Untold' the 36-year-old admitted to getting a bit carried away during the fight scenes with his co-star.
The ‘Mamma Mia!’ star was left feeling ‘terrible’ when he almost ‘poked his eye out’ with a sword.
Despite the accident, Dominic enjoyed working on the film and loved playing villain Mehmed because it allowed him to be more daring and ‘over the top’.
In an interview with Shortlist magazine, Dominic said: "I nearly poked Luke's eye out with a sword. We were trying to be careful and not use metal swords, and I think because of movement within the sword it bounced back into his eye - so I don't take full responsibility. It was pretty terrible."
He added: "Mehmed is a terrifying man and desperate to take over the world. I love parts like this because you can be daring and they're quite eccentric and over the top. And I'm wearing golden armour."
However, the actor is unsure anyone will be impressed with his linguistic skills in the move.
He added: "I learnt a lot of Turkish - it'll probably be laughable, but I can pretend."
