<P> Harold & Kumar began filming on May 12 , 2003 . The film is set in New Jersey , but was mainly filmed in Toronto , Ontario , Canada . Scenes set at Princeton University were actually filmed at the University of Toronto 's Victoria College and Knox College . The production design team had to build a White Castle franchise especially for the shoot since Canada does not have White Castle restaurants . During filming , Penn ate veggie burgers as he is a vegetarian . </P>
