Tom Cruise has been filming the latest installment of Mission Impossible in Europe for quite some time, and this weekend he had to let off a building — but he ended up slamming against a brick wall.

While he was a attached to a pulley system, he was still injured as his knees buckled beneath him. He was clearly in pain, but told crew members not to help him.

The actor ended up limping away and finish filming the scene. It’s unclear what these injuries are, and if they’re going to stall filming.
