Seann William Scott
Steve Stifler remains one of the most iconic and notorious teen movie characters. Scott played the loudmouthed, party-loving bully and immortalized him forever. He made millions from the American Pie franchise and won acclaim for his charisma. But Scott enjoyed a more subdued subsequent success (via Best Life Online).
He lent his voice to the Ice Age saga and appeared in random low-budget movies or TV shows. Nobody can say that Scott’s career is unsuccessful. However, it’s safe to say that he didn’t reach the levels of fame that people may have expected. Scott may prefer this because too much celebrity is a nightmare to live with.
