Rent Lucky Jim (1957)

Jim Dixon doesn't feel very lucky at all, working as a junior university lecturer with the boring and tiresome Professor Welch. So when Jim finds out he has to spend a whole weekend at his house to help save his job he can't think of anything more unpleasant... But it only goes from bad to worse as he manages to get himself and the family dog blind drunk and falls in love with the rather beautiful Christine, who just happens to be Welch's son's girlfriend... When Jim is given a second chance to save himself and his job all he has to do is deliver a lecture at the university, but some things are easier said than done!
