Christopher Nolan says he would be a ‘happy man’ if he could have Cillian Murphy in every film he ever does

Cillian Murphy has appeared in five Christopher Nolan films during his lengthy career, with an upcoming sixth called Oppenheimer that is yet to drop.

It's safe to say that the chemistry between them produces magic as The Dark Knight trilogy, Dunkirk and Inception are phenomenal films.

We could see plenty more of the Irish actor in the legendary director's films if the latter has his way.

When asked if Nolan had become sick of working with Murphy after all these years, he gave a pretty wholesome answer.

"If I could cast Cillian in every film I ever do, and just lean on him for the rest of my career, I'd be a happy man."

Well, that is certainly one definitive answer.

Despite working on six films together, it was their latest that brought Nolan so much joy when it came to the casting process.

Murphy plays theoretical physicist J. Robert Oppenheimer, who was the head of the Los Alamos Laboratory-based Manhattan Project during World War II.

Oppenheimer is largely credited with creating the first atomic bomb and the film dives into the journey of its manufacture.

While Murphy has played pivotal roles in Nolan's previous films, he gets to be the lead in this one.

Nolan told Entertainment Weekly: "To be able to pick up the phone, and call you, and be like, 'This is the one where you carry the movie and really get to show what you can do', it's honestly one of my favorite moments in the movie business, when I had that conversation with you."

Murphy added: "It was one of the best days of my life, I'll tell you that, when you called me.

"I'll always turn up for Chris, no matter what the part is, but, secretly, it's a dream to play a lead part.

"The thing was, I had no idea.

"There was no preamble or anything, I just got the call. So it was incredibly exciting, and daunting, and terrifying, all at the same time."

Cillian hadn't even read the script for Oppenheimer at this point but he was just thrilled to be part of the project.

However, once he did feast his eyes on the content, he was blown away.

Murphy said it is the best script he's ever read and that is certainly a big statement.

We can't wait to see him in action as the controversial scientist when the movie drops on July 20.
