Ken Jeong's height is something of an optical illusion. You probably realize that he isn't the tallest actor in the world - in fact, you likely always assumed he was short - but in Jeong's case, he may actually be slightly taller than you thought he was. Would you be surprised if we told you he was exactly the same height as Daniel Radcliffe, at 5 foot 5? If so, be surprised - because he is!
Jeong is a comedy actor who almost got into the profession by accident. His most prominent roles to date have probably been in the hilarious 'Hangover' series of movies, but you've likely also seen him in 'Knocked Up,' 'Role Models,' and several other places. If there's an accident or injury on set, he'll be the first one on the scene - he's a fully qualified doctor, and had to be persuaded by an agent to give it all up and follow a career in the acting profession. Our congratulations to his agent.
