Rupert Cadell: Well, well, well, Kenneth Lawrence, how you've grown.
Kenneth: Hello, uh, Mr.
Rupert Cadell: Come on, Ken. School's out, you can say it.
Kenneth: Rupert, you're the same as ever. It's awfully good to see you again.
Rupert Cadell: Why?
Trivia: At first, this film seems to have only one scene and two shots, one outside and another inside. Actually, it is divided in a series of 10 minute continuous shots, 10 minutes being the maximum duration of filming possible without reloading the camera. Every 10 minutes, the camera zooms on a dark object and then cuts.
