After so many years of only knowing about it, I finally watched this on YouTube just now. Michael Landon plays the title character as Tony Rivers, who is rebellious because...well, just because as it takes a while before some kind of explanation is provided. Yvonne Lime is his girlfriend and Whit Bissell is the shrink who provides the "solution" that causes his changes. Among the people who crosses the werewolf's path is one Dawn Richard who would become a Playboy Playmate a few months before this movie's release. I'll just now say while there were some exciting scenes, some of the tone was uneven as we go from Tony's frustrations to his being more joyful during a party scene to his being more behaved after his visits to his shrink. And you have to wonder if the shrink really thought his experiments straight through. Still, this was quite a thrilling ride despite the obvious low-budget and short filming schedule. (Only seven days!) And Michael Landon seemed never to have been shamed by his appearance in this movie as he's spoofed himself over this part of his past on shows like "The Donny and Marie Show" and his own "Highway to Heaven". So on that note, I'm glad to have finally seen I Was a Teenage Werewolf and recommend it with no reservation!
