While speaking at the Loyola Marymount University School of Film and TV's 'The Hollywood Masters' series, the 72-year-old actress, said it "wouldn't be hard" to penetrate Trump's psychology, according to The Hollywood Reporter.
"I'd be so funny as Trump. I love it. I've almost got the hair! I mean what a fascinating character. What an extraordinary character. I mean that's a character isn't it, the real thing? I would say real life is so much more interesting than anything you can make up, you know," noted Mirren.
"But you know, a fantastic sort of slightly Shakespearean character. He may have a Shakespearean fall, I don't know but you know, he is an extraordinary character."
The 'Collateral Beauty' star added that she didn't foresee getting into the President's head to be much of a challenge.
She said, "I don't think that would be too difficult to penetrate quite honestly. You look at the upbringing. You look at the schooling, the father, the mother. I don't know much about Mr. Trump's background, but if I was to play him, I would definitely start there."
Donald Trump has been a popular impersonation for decades, even before becoming president, parodied by the likes of Johnny Depp, Alec Baldwin, Jimmy Fallon, Darrell Hammond, and even another Oscar-winning actress Meryl Streep.
Mirren, though, would go further than simply an impression, and explained that in order to play a character like Trump right, you have to go way back.
"That's what you have to start with, the child, you know and the child is very much in Trump," explained Mirren.
Meanhwile, on the professional front, Mirren will be next seen in 'The Leisure Seeker' alongside Donald Sutherland. (ANI)
