Kevin Smith had a problems with Bruce Willis on the set of “Cop Out,” but they didn’t fall out. Which one is it, exactly? In a 2009 interview, the director of “Clerks” described the action hero as “undirectable,” but subsequently added, “I think somebody took it as a negative. It’s not like, “Ahh, I can’t deal with him!” It’s just how do you direct Bruce Willis to play Bruce Willis? I can direct Jason Mewes to play Jay. I can direct Affleck to play a fucking angel — or to kill his career as a grieving father. But I can’t fucking tell Bruce Willis how to be Bruce Willis — cause he’s fucking Bruce Willis!”

However, Smith now appears to be more open to discussing what really transpired during the filming of the buddy cop comedy, admitting that working with Bruce Willis on Cop Out was “soul crushing.”

Smith was a recent guest on Marc Maron’s famed WTF show, where he ripped into the 55-year-old Thespian.

He said, “It was difficult. I’ve never been involved in a situation like that where one component is not in the box at all. It was fucking soul crushing.”

Willis also allegedly declined to sit for promotional images for the film’s poster, he claimed.

“A lot of people are gonna be like, ‘Oh, you’re just trying to blame the movie on him’,” he said. “But I had no fucking help from this dude whatsoever.”

Both Willis and Smith grew up in New Jersey, and the filmmaker claims to have been a long-time fan until he met the real Bruce Willis.

Smith joked with show presenter Marc Maron that he’ll never have to explain his late father that his movie idol isn’t truly a hero.

Maron remarked, ‘Honestly, you were given the gift of not having to tell your dad that Bruce Willis was a d***.’

‘I wish he could’ve just communicated it to me from the afterlife,’ Smith added.

In a previous interview, Smith essentially singled out Willis, claiming that just one person on the set was pleasant to deal with, and it wasn’t him. “Tracy Morgan, I would lay down in traffic for. Were it not for Tracy, I might’ve killed myself or someone else in the making of that movie.”

So, why did Smith accept the director’s job on “Cop Out” when Warner Brothers offered it to him in the first place, based on a script he hadn’t written? He explained, “I needed to see marketing from the inside for some shit I got comin up.”

The National Enquirer claimed in Summer 2009 that Willis was notably absent from the film’s wrap party, where Smith said remarked “I want to thank everyone who worked on the film, except Bruce Willis… who is a f**king d**k!” Willis refused to accept direction and was “very much the author of his own performance,” according to Smith, so it took him a long to figure out how to work with him.

Based on the teaser trailer we’ve seen, his next American-set horror “Red State” seems fairly excellent. Perhaps Smith has found his new calling.
