George Clooney isn't taking Donald Trump's run for president seriously - and he doesn't think history will either.

During a Toronto Film Festival press conference for his film Our Brand Is Crisis, Clooney didn't hold back when it came to Trump and the GOP frontrunner's remarks about Mexican immigrants.

"Clearly, what he said is idiotic, of course it's idiotic," Clooney said, according to Us Weekly. "Anybody who says as intolerant words as those should be laughed at and that's pretty much [what] I think eventually history will do."

In June, Trump made offensive remarks about Mexicans, referring to them as criminals and rapists. "The U.S. has become a dumping ground for everybody else's problems," he said at the kickoff event for his campaign. "They're sending people that have lots of problems and they're brining those problems with us. They're bringing drugs. They're bringing crime. They're rapists. And some, I assume, are good people."
