Após comentário de steelersquirrel Eu fiquei sabendo que See You Next Wednesday é uma piada recorrente em Filmes de John Landis:
See You Next Wednesday is a recurring gag in most of the films directed by John Landis, usually referring to a fictional film that is rarely seen and never in its entirety. Each instance of See You Next Wednesday in Landis's films seems to be a completely different film.
Mas este blog apresenta uma análise muito detalhada do significado do filme:
The trademark trivia often mentioned in Landis directed films, the inclusion in some form of the phrase “See you next Wednesday” is a reference to a line in the Stanley Kubrick film ‘2001: A Space Odyssey’ where astronaut Frank Poole watches a video sent to him by his wife and father on the occasion of his birthday. At the end of the video his wife says, “See you next Wednesday!” an obvious reference to their next available time to transmit a message to the distant space craft bound for Jupiter, though since Frank is killed within the next day or two by HAL, it is perhaps meant as an ironic trademark since it seems to occur in Landis films when characters are in great danger.
O mesmo acontece em Um Lobisomem Americano em Londres também, onde David encontra seu trágico destino logo depois de ver See You Next Wednesday . Mesmo antes disso, um personagem morreu no metrô quando passou pelo cartaz do filme:
