One of the worst mistakes you can make as a smaller person is to spend all of your time hanging around with much taller friends. All it does is make people notice your height when you take pictures together! We can't really begrudge Hart's choice in friends though - if our best buddy was Dwayne 'The Rock' Johnson, we'd spend all of our time hanging around with him, too. Anyone would look small next to Johnson - he's a monster of a man - but in Hart's case he'd probably look a little small no matter who was standing next to him.
Like Martin Freeman, Hart has never confirmed his true height, so all we can do is try to work it out based on pictures of who we've seen him standing with. Using that highly scientific method, we think he's probably around 5 foot 4. They do say good things come in small packages, though, and Hart has been a great package of laughter for many years now. He occasionally courts controversy, but that's inevitable when you're an edgy comedian.
