The 'Jason Bourne' star is up in arms over the issue.
Weeks after the Orlando shooting, Matt Damon is speaking out on gun control.
The 45-year-old actor opened up to The Sydney Morning Herald while promoting his new film, Jason Bourne, where he stated that he wishes the U.S. would follow Australia's lead in implementing strict gun control legislation.

"You guys did it here in one fell swoop and I wish that could happen in my country, but it's such a personal issue for people that we cannot talk about it sensibly. We just can't," Damon told the newspaper.
"People get so emotional that even when you make a suggestion about not selling AK-47s to people on terror watch lists, that's a non-starter," he explained. "I don't know what needs to happen. Obviously mass shootings aren't going to do it. There have been so many of them at this point. Sandy Hook, when those children were murdered, if that didn't do it, you know, I just don't know. Maybe we just need to evolve further before we can have that conversation, I don't know."
"It's wonderful what Australia did because you guys haven't had a mass shooting since you went, 'No, we're going to be sensible about this.' And nobody's rights have been infringed, you guys are all fine," The Martian star said, before adding that he sadly doesn't believe gun reform will happen in his lifetime.

Damon isn't the only actor in Hollywood taking up the cause of gun control.
Danny DeVito opened up to ET's Ashley Crossan just two days after the Orlando massacre, and revealed how heartbroken he was about the shooting, and outraged that the gunman used a weapon originally designed for U.S. Special Operations forces.
"I can't get over it…It's a gun that we shouldn't have in our country. It's one thing to have a hunting rifle or a target pistol, but this gun is just made to butcher people. It's an awful, awful thing, and we just let it go. You and I and everybody out there, we have to figure out a way to stop them," the 71-year-old actor pleaded.
"The only people who can get rid of the guns are people. We can go march in the streets and say, 'This can't be.' We can't let this continue," he said.
