I haven't been out this way in years. This is a question that I asked before and someone knew of it. A TV movie, mid 1970s I think, cel animated in the "Archie" style. Lots of nighttime scenes, and there is a teen werewolf contagion! It had a title like "Moonlight Becomes You" or something similarly poetic. And the overall sense of menace was quite a lot. Played fairly serious, and not much for laughs.
