"People weren't expecting him to be physical because he's quite a pretty boy, but he was a dude and got in there and did all the fight scenes. He was great," he said.
The 38-year-old star also revealed he was inspired by JJ Abrams to do more filmmaking
"JJ is a very inspirational guy. He leads from the front and has a positive energy on set. When you have someone like that at the top, it filters on down through the crew," he added.
