Aside from William Shatner playing himself in Free Enterprise, Neil Patrick Harris?s small part in this movie is probably the greatest celebrity cameo in the history of film. I also enjoyed this bit of Lawrance Bernabo?s review of the movie on Amazon: ?This film is in the great tradition of ?Dude, Where?s My Car?? and ?The Lord of the Rings??. That is indeed a fine tradition. Now if you?ll excuse me, I need to plan my trip to White Castle for lunch today.
