Justin Jacob Long (born June 2, 1978) is an American actor, comedian, director and screenwriter. He is known for his work in comedies (like Accepted and Dodgeball) and horror films (like Jeepers Creepers, Barbarian, and Weapons). In recent years, he has been labeled a scream king. He has done voice roles as well, including as Alvin Seville in the live-action Alvin and the Chipmunks film series. He is also known for his personification of a Mac in Apple's "Get a Mac" advertising campaign (2006–2009), and appeared as himself in Intel's "Go PC" campaign.
