Kevin Smith has taken on everyone from film critics to movie distributors to airline companies--so it should come as no surprise that the outspoken filmmaker isn't the type to forgive and forget.

Though the tweets have since been deleted, Smith, 41, shared an excerpt from his new book, Tough S--t: Life Advice from a Fat, Lazy Slob Who Did Good, on the social media site Thursday. "Who am I talking about when I write THIS," Smith tweeted. "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."

Fans of the filmmaker quickly guessed the actor at the receiving end of Smith's insult: none other than Bruce Willis, whom he directed in 2009's Cop Out. Shortly after Cop Out shooting wrapped, Smith called Willis, 57, "undirectable."

"Bruce Willis is probably the most intimidating actor I've ever worked with," the Red State director told reporters at the time. "He has all sorts of range, but what he's predominantly known for is playing the guy who holds his gun down by his side and saves people. How do you tell Bruce Willis to be Bruce Willis?"
