The Making Of The MCU: 17 Fascinating Behind-The-Scenes Details You Need To Know

Marvel Studios is one of the most secretive movie companies out there, employing all kinds of covert tactics like inserting fake shots into trailers to lead fans astray, or refusing to give its actors full access to movie scripts.

This level of mystique also extends to the studio's casting process, which is something Mark Ruffalo learned while vying for the Hulk job.

Ruffalo knew that if he got the role, he'd be appearing onstage at Comic-Con 2010, which obviously sounded exciting. But the way Marvel Studios actually told him he was successful probably left the actor feeling rather stressed:

"I got a call saying 'wake up tomorrow at four o'clock in the morning. Look out your window. If there's a limo there, you're doing the part. If not, go back to bed.'"

That limo ended up taking him to the plane that would fly him to San Diego, meaning that Ruffalo had no time to process his casting before he was thrust into that glaring Comic-Con spotlight. Not cool, Feige. Not cool.
