No one could have played Joey quite as well as Matt LeBlanc, that’s for certain. But the role almost went to another actor, who also later appeared on the show as Joey’s twin. LeBlanc auditioned at NBC alongside actor Louis Mandylor. LeBlanc didn’t have much experience but the creators loved the way he delivered the lines so the role ultimately went to him. Ironically, Mandylor returned to the show years later for “The One with Unagi” episode. In the Season 6 episode, Joey hires a fake lookalike named Carl to play twin, and it was played by Mandylor.
