Josh Harnett's Stunt Nightmare

Movie actor Josh Hartnett was left concussed after a stunt went wrong while filming his movie Hollywood Homicide.

The Pearl Harbor hunk suffered the injury when a stuntman drove his vehicle into a fake cop car, which had him and co-star Harrison Ford inside.

He tells British radio station Radio 1, "It was quite an accident. Because we didn't have airbags it was worse. I hit my head and got concussion and he [Ford] pulled his groin.

"But it was this stunt driver, who will obviously remain nameless, did something completely different from the rehearsal take, and basically slammed right into us."
