Ben Affleck has revealed that playing a chainsmoker in new film Smokin’ Aces actually helped him give him the habit in real life.

He said recently: “The whole week that I shot, I smoked, like, five packs a day.”

“By the time the movie was over, I was so sick of smoking, I just didn’t want to do it anymore, and I quit.”

“It’s pretty cool that I have this celluloid record of the last time I smoked.”
