“Poor Kevin. He's just a whiner, you know? We had some personal issues about how we approached work,” he told Time Out.

“I don't have an answer for him. I'm never going to call him out and lay him out in public. Sometimes you just don't get along.”

Smith deemed Willis 'undirectable' at the time, and called him 'the most intimidating actor I've ever worked with'.

“Were it not for (co-star) Tracy [Morgan], I might have either killed myself, or someone else in the making of 'Cop Out',” he said, while Willis countered: “[Smith] smokes way too much pot. He sat behind his monitor. He didn't interact with the actors. The actors felt they were on their own.”

Smith later described Willis in his book 'Tough S**t: Life Advice From A Fat, Lazy Slob Who Did Good' saying: “He turned out to be the unhappiest, most bitter and meanest emo-bitch I ever met at any job I've held. And mind you, I worked at Domino's.”
