US film industry website Deadline reported that O’Brien fell off the back of a set that was supposed to look like the back of a train while shooting the third film in the post-apocalyptic adventure series, The Death Cure. He sustained a fracture to either his cheekbone or eye socket and is being treated in a local hospital.

Celebrity website TMZ had earlier said that O’Brien was injured in a scene involving a car and may have suffered multiple broken bones.

A spokesperson for movie studio Fox said that production will be shut down while O’Brien recovers.
