Flynn from the Disney movie Tangled was supposed to be British!

Zachary Levi, the voice of Flynn, won the role speaking with a fake British accent. It was later decided that Flynn would be American. Levi is probably best known for playing the main character in the TV show Chuck. Flynn can be found at Walt Disney World and Disneyland doing appearances, as well as Fantasyland in Florida in Epcot.

Another fun fact about Flynn is that he's only the second Disney Prince to be a thief. Aladdin was the first thief.
