Justin Long Won't Say Anything Bad About Bruce Willis... But He Also Won't Say Anything Nice

Kevin Smith had no problem trashing Bruce Willis on Marc Maron's podcast in 2011, describing his experiences directing the actor in "Cop Out" as “soul crushing." But Justin Long, who stars in Smith's new film "Tusk," refused to do the same in a HuffPost Live interview Wednesday -- though he noticeably didn't have anything nice to say about Willis either.

When asked about what it was like to work with Willis in "Live Free Or Die Hard," Long first jokingly threatened to walk off the set. He then explained to host Ricky Camilleri that he doesn't want to "disparage anybody or speak ill of anybody" that he's worked with.

"I will say this, I have worked with people who are difficult in the past and I've made an effort to not talk about it publicly," he said. "I just don't think it serves anybody. I know that's a really lame, boring answer. I'm sorry."
