Iron Man. Captain America. Thor. Doctor Strange. Spider-Man. Ant-Man. Guardians of the Galaxy. The Avengers. The Marvel movie machine is unstoppable, cranking out multiple flicks each year that send fans into a frenzy and dominate global box offices.
With success practically guaranteed, it's no surprise that some of the greatest actors in the world are lining up to play heroes from the Marvel comics.

The improvised details that make the final cut are often easy to miss, so Screen Rant decided to reveal 10 Marvel movie moments that weren't in the script. Check out the vocal stylings of Sir Anthony Hopkins, the snack habits of Downey Jr, and more in the clip above.
