"We didn't watch many films in preparation for Teenage because licensing features is incredibly expensive. Also because there weren't that many specifically about youth culture as something different from adult culture. On the other hand there were some significant films that were about the problems of youth that were taken up by the youth audience. One of them is It starring Clara Bow, the original 'It Girl'. Clara Bow is the most amazing screen presence, a huge silent star. She was fantastically sexy but also very alluring. One of those people that just lights up the screen when she's on it. A lot of people thought It was rather scandalous and tried to ban it. In the film she's a working girl but beautiful and cheeky, who marries a rich guy, so it's a classic Hollywood fantasy fulfilment role, one of the first times it was done. There was a whole moral panic about the movie and Clara Bow, so it was very popular amongst kids. There are earlier teenage films like Flaming Youth from 1923, but we don't know if a print still exists, we tried to find one and couldn't. There's a whole phase of college movies from the twenties and they've all disappeared."
