As famous and loved around the world as the character of Homer Simpson is, we suspect that most people wouldn't want to be known as the real-life version of the goofy character. For that reason, Paul Giamatti has our sympathies. In fairness this isn't his fault - by the time he got his career break in 1997 with 'Private Parts,' 'The Simpsons' was already very well established. The fact that he bore a strong physical resemblance to Homer wasn't exactly something Giamatti could do anything about by then. He's just had to roll with the punches.
What can be said about the father of the Simpsons family that hasn't already been said? He's one of the most famous TV characters of all time, and directly inspired Peter Griffin in 'Family Guy.' The senior Simpson is a lovable idiot, who the whole world has affection for despite his complete incompetence as a father. Giamatti may look like Homer, but we have no doubt he's far more intelligent.
