was just curious of his early film and mr universe stuff, Stay Hungry etc, so refreshed memory. in 1977 Arnie played himself in this film. Imdb says in 1969 he was in Hercules in New York and then in 1973 he had a cameo as hood in The Long Goodbye with Elliot Gould. Arnie even appeared in an episode of Streets of San Francisco in 77 as well, opposite Maldon and Michael Douglas.
