In an attempt to explain why he’s not Jason Bourne anymore, Matt Damon made sure to ruin the career of at least one person in Hollywood.

In a recent chat with GQ magazine, Damon said that screenwriter Tony Gilroy was phoning it in with The Bourne Ultimatum script.

“It was unreadable,” Damon said. “This is a career-ender.”

Damon was all set to go on the forth installment in the franchise, but after they kept pushing it without having a script in place, both Damon and the movie’s director decided to pull out.

Damon continued his rant about the first draft of the script:

"I could put this thing up on eBay and it would be game over for that dude. It's terrible. It's really embarrassing.”

Matt. You were in EuroTrip. I don’t even wanna hear it.

“He was having a go, basically, and he took his money and left,” Damon continued.

I guess Damon felt bad after that, because he called the GQ reporter back up and told them:

"My feelings were hurt. That's all. And that's exactly why I shouldn't have said anything. This is between me and him. So saying anything publicly is f-cking stupid and unprofessional and just kind of douchey of me."

And despite his outburst, Damon said: “If I didn't respect him and appreciate his talent, then I really wouldn't have cared (to apologize)."
