Oscar-winning trio Tom Hanks, director Ron Howard and producer Brian Grazer are bringing 'Angels & Demons' to the big screen this summer, and ET was the only show with exclusive access to the top-secret set at the Vatican City in Italy. Get an exclusive look at a scene from the movie here!

The exciting prequel to 'The Da Vinci Code' finds Tom's world-renowned Harvard symbologist Robert Langdon confronting a shadowy secret society, the Illuminati, to uncover a conspiracy that may put the Vatican -- and the world -- in explosive jeopardy.

Mary Hart spoke with Tom about the film and our special footage of a cardinal in fiery danger on the red-carpet at The Golden Globes, and he told her, "Well, it was fiery, it was hot. It was a physical day. I kept begging Ron to go ahead and let a stuntman do it all -- I'm not that way -- and yet he insisted I do it. So I had to do a lot of climbing, crawling, being on fire, pretending I was on fire."

'Angels & Demons' hits theaters May 15.
