A good place to start - a movie from 1936 predicting the future of a post apocalyptic world.

Living in a part of the world where nothing changes very rapidly means 2050 won't be too much different from today (less cars, same street layout, more horse cr*p) just as 1970 wasn't to different. The waterfront development in my city has been scheduled to be completed (there is a sign in the town centre saying the work is due for completion by 2031) just before Everytown was rapidly constructed by 2036 in the film.

The local pub (been operating since 1870) I suspect will probably be under different management by 2050 though and the beer probably won't be as good by then.
