15 Actors You Totally Forgot Were In DC Comic Book Movies

14. Jack Gleeson

The Movie: Batman Begins

Role: Little Boy

Who He Played: A little boy living in the Narrows encountered separately by Batman and Rachel.

It might sound questionable, but Jack Gleeson didn't actually arrive on this Earth fully formed as the bile-spitting, brat king of Westeros. He had a career before that, starring in the likes of Reign of Fire, Shrooms in 2007, and A Shine of Rainbows. Clearly, none of them were as important as his minor role in Batman Begins.

The boy who would be Joffrey played a young boy living in the Narrows who meets both Batman and Rachel separately. Given how different he is to his Game Of Thrones appearance, it's shocking to see him in Gotham now when you watch back.
