31 celebrities you didn't realize are really short

It's hard to judge actor's heights on screen.

And sometimes, extreme steps are taken to make folks seem taller than they actually are. Some step on boxes or sometimes camera angles are changed up.

While some short actor heights are known, some others might come as a surprise. 

Here are 31 actors you might not know — or remember — are short:

Standing next to the 6' 4" Khal Drogo (Jason Momoa), the 5' 2" Mother of Dragons (Emilia Clarke) looks tiny.

Maisie Williams and Sophie Turner might only be a year apart, but the "Game of Thrones" costars stand at 5' 1" and 5' 9," respectively.

And at 5' 8" Kit Harington is an inch shorter than Turner and seven inches shorter than the the 6' 3" Gwendoline Christie.
