Ewan McGregor Got Hurt Doing What to His Haywire Costar Gina Carano?

Exclusive! Find out how the actor almost broke his hand while making new action thriller

You gotta hand it to Ewan McGregor.

He suffered one injury while making the new action thriller Haywire, but he's not embarrassed to say what really happened.

Sure, he could claim he hurt his hand doing some sort of crazy stunt, but no...

"The only time I got hurt was when I punched Gina Carano in the head by accident," McGregor told me at the Golden Globes.

For those not familiar, Carano is a mixed martial arts champion who makes her big screen debut in Haywire (out tomorrow) as a former federal agent on the run from assassins. The Steven Soderbergh-directed flick also stars Channing Tatum, Michael Fassbender, Antonio Banderas and Michael Douglas.

"I had a series of three punches, but the third one...for one reason or another I connected really hard on the side of her head," McGregor said. "She was the one who got straight up and said, 'Are you OK?' She was asking me if I was OK! But she was right because I almost broke my friggin' hand!"

Carano took the hit like a champ. McGregor laughed, "She was absolutely fine."
