Have you ever watched a cartoon character and been reminded of someone else? That might not be simply a coincidence, as there are plenty of cartoon characters based on real life people. Animation studios used actual humans to act as visual and live-action reference for the cartoonists to bring their creations to life as realistically as possible.
And then famous actors also inspired certain characters. Sounds pretty cool, huh? But not everyone has been happy about his or her likeness being used.
