There were two Harold Teen pictures, a 1928 silent starring Arthur "Dagwood" Lake as Harold, and then the 1934 talkie with Hal LeRoy. The latter is a really fun little picture with a couple of excellent songs, and LeRoy, who was possibly the greatest eccentric dancer on Broadway in the 30s, is - haircut aside - just perfect as Harold. It was intended to be the first of a series, but for whatever reason they never carried on with it. I haven't seen the silent, but those who have say it's even closer to the actual strip. Both the 1928 and 1934 pictures had location footage shot at the actual Covina High School in Covina, California -- which was the origin of "Covina" as the name of Harold's home town. The comic-strip Covina is definitely not in California -- it's somewhere in Illinois -- but that's but a small point of order.
