Domhnall Gleeson lost so much weight for Angelina Jolie's new movie Unbroken his contact lenses no longer fitted his eyes.

The actor got serious about looking like an emaciated prisoner-of-war in the upcoming Louis Zamperini biopic and even Jolie was impressed with how far her went to achieve the perfect look for the film.

Co-star Jack O'Connell tells Wenn, "Domhnall lost so much weight even his eyeballs changed shape! He dropped a contact lenses size!"

Castmate Finn Wittrock adds, "He came back and his contact lenses didn't fit anymore!"

Jolie states, "They had to wear contacts for all the red lines and they fit when he was starting to lose weight and then when he got to the end of the section in the raft they wouldn't go into his eyes. I think it was the dehydration... It was really impressive."
