PHOTOS: Marky Mark is struggling

, LOS ANGELES, CALIFORNIA - Monday March 15 2010. A puffing and panting Mark Wahlberg, films a running scene for his latest movie "The Fighter" in Los Angeles. The former Calvin Klein underwear model has gained quite a few pounds for his role as a boxer in the new film. So much so, that he now has a double chin. British actor Christian Bale also stars.
