George Costanza is Based on Larry David
George Constanza is based off of the co-creator of the show and star of “Curb Your Enthusiam,” Larry David. Although, his last name is actually taken from the other co-creator of the show, Jerry Seinfeld’s real life friend and college roommate, Michael Costanza. His middle name Louis is homage to Lou Costello of the comedy duo Abbot and Costello.
