Actor Bryan Cranston has a profanity-laced warning for anyone hoping the Trump presidency doesn't succeed.

"It would be egotistical for anyone to say, 'I hope he fails,'" Cranston told the Hollywood Reporter in an interview published Monday, referring to President Trump. "To that person I would say, fuck you. Why would you want that? So you can be right?"

Cranston, best known for his turn as Walter White in AMC's "Breaking Bad," was a vocal critic of Trump in the lead-up to the 2016 elections.

But he admitted "it’s just astonishing" how his opinion has morphed since the president's inauguration.

"President Trump is not the person who I wanted to be in that office and I’ve been very open about that," he continued. "That being said, he is the president. If he fails, the country is in jeopardy."

Cranston said hyper-partisanship was preventing lawmakers from solving pressing policy problems, adding there needed to be a paradigm shift away from "this idea that our country is [a] political football and someone with a different opinion is the enemy."

Instead, he said people should "assume they love this country as much as you do.''

"If you’ve got a good idea that helps the country, oh man, I’m gonna support you," he said. "I don’t care if you’re a Republican and I’m a Democrat or whatever, I don’t care. A good idea’s a good idea."

Cranston is currently promoting his new film, "Last Flag Flying."
