Matt Damon had to double check he hadn't hurt his co-star Hailee Steinfeld every time they filmed a fight scene in True Grit.
In one controversial scene, 14-year-old Hailee's character Mattie is slapped by Matt's character LaBeouf.
Hailee said: "I thought it was fun, and also funny. After every take, Matt would ask if I'm OK and that I wasn't hurt."
The actress added that working with Matt, Jeff Bridges and directors the Coen brothers was a good laugh.
She said of the directors: "They're really big kids...They are amazing. You know when they like something - they just giggle."
And Jeff revealed he and Hailee played Pass The Pigs in between takes.
"Her pig was Bo Bacon, and mine was the Pig Man," he said.
