Brad Pitt, Jimmy Fallon Yodel [VIDEO]: 'World War Z' Star Stops by 'Late Night' for Special NYC Rooftop Duet, Says Angelina Jolie is 'Doing Great'

Brad Pitt premiered his latest movie, World War Z, in New York City on Monday and then stopped by "Late Night with Jimmy Fallon" the following day for a special yodel duet with the host. The two shared an interesting conversation across the Big Apple's rooftops and then decided to attempt a duet of yodeling, which had reportedly never been successfully done before. Clearly this bit for "Late Night" was just a fun way to mention Pitt's new film, but it was definitely entertaining.

Check out the video right here:

During Monday's premiere of World War Z, Pitt was taken aback by the crowds of fans who came out to catch a glimpse of the star. Pitt, who also produced the film, was not accompanied by Angelina Jolie like he was at the London premiere, but he assured everyone that she is doing fine.

"She's doing great. Onward and upward," he said.

World War Z is based on Max Brooks' novel of the same name and focuses on a world getting taken over by the undead (everyone involved with the film has yet to say "zombie"). Brad Pitt portrays a United Nations investigator who may be able to figure out what caused all of this madness, and Mireille Enos (The Killing) plays his equally tough wife.

So does Pitt relate to his character who believes that "movement equals survival"?

"I don't have a single mantra," he said. "It's just spending time with the people I value. I like calling shots on the fly and having faith in myself to make the right decisions. Wisdom comes with age. I like it!"

As for Enos, she stunned the crowd in a J. Mendel dress. "This process started at around 3:30. My daughter ran around while I was getting ready and said, 'Mommy looks beautiful,'" Enos said, smiling
