Jon and Dan Heder
Jon Heder is most famously known for his role in Napoleon Dynamite, but something that you may not have known is that Jon has an identical twin brother named Dan, who also works in the film industry. Dan has starred in a couple of films but mostly likes working behind the camera. The twin brothers own a production company called Greasy Entertainment and have been working together for years.
The twins are very hard to tell apart, and Dan has had several encounters where people believe he is actually his brother and he has had to convince them that he is his twin.
