The intention of this movie is to make fun of a pretentious art film using Freddie Blassie, the most bombastic, crude, and intellectually offensive personality in the media at the time. He was a legendary, loud-mouth wrestler known for calling his opponents, and anyone else he disliked, "pencil-neck geeks". (I remember he once held "geek" ringside announcer Dick Lane upside-down outside a window in the middle of a telecast.)
However, Kaufman's and Zamuda's cynical snot and vomit routines, no doubt intended to provoke Blassie into a rage, backfire. Although Blassie never seems to be "in" on the joke -- he is genuinely offended by (or blissfully ignorant of) Andy's mocking behavior -- Blassie comes across as warm, good-humored, brutally honest, and full of the love of life. Towards the end, Andy seems genuinely in awe of Blassie whose rich stories and politically-incorrect observations contrast sharply with Andy's feigned(?) shallowness and politeness.
Overall, this is a good film and very funny in places, but I came away more in admiration of Freddie Blassie than Andy Kaufman. Were it not for Andy's more imaginative routines in television, I would have a very poor impression of him. Nonetheless, I enjoyed this film, which, if nothing else, gave me an overwhelming nostalgia for Sambo's pancakes.
