Kevin Smith, Bruce WillisDirector Kevin Smith has an opinion of Bruce Willis, and he's not holding back.

According to the Daily Mail, Smith recently went on the 'WTF with Marc Maron' podcast and slammed Willis' committment and attitude while shooting 2010's 'Cop Out,' which Smith directed.

Smith claims the actor neglected to promote the film, contributing to the movie's lackluster performance in theaters. 'Cop Out' grossed just $44 million in North America.
