Josh Hartnett says he is obsessed with boxing.
The sexy actor says training to play a boxer in flicks like Black Dahlia and Resurrecting the Champ made him love the sport.
“The first time I got in the ring I became immediately obsessed and I started watching a lot of boxing films of full fights and I started to over train,” explains Josh.
“I just found it so interesting – the dynamics of fighting and how the best fighters are so intelligent. I still love the boxing world now.”
