Aaron Eckhart has confessed the toughest challenge of playing the US President was sharing the screen with Morgan Freeman.
The Dark Knight Rises star plays the world leader in action movie Olympus Has Fallen, alongside 75-year-old award-winning actor Morgan, who has previously played the President in disaster movie Deep Impact, but in this new movie plays the Speaker of the US House of Representatives.
Aaron revealed: "I think the biggest challenge of playing the President was Morgan Freeman... I was standing very presidentially in the Oval Office by the desk and I was waiting for everybody to come in, and then Morgan Freeman walked in and everybody thought he was the President. So I was like 'I'm the President of this movie!'."
The 45-year-old actor admitted the President of the United States was a role he had always dreamed of.
He confessed: "It's interesting as an actor playing a President, because every American kid grows up wanting to be a President."
California-born Aaron grew up in Kent and was proud to premiere his new film in London.
He revealed: "I saw the poster on the side of a bus and thought 'Jeez, you've come a long way!' I started my theatre career here in London and it's been a long time. I love theatre, I love film and it's good to see your name on a double decker bus! It's an achievement."
