Well hopefully the people there will tell you which films to watch.
I would suggest Citizen Kane, often voted the best film of all time.
This was Orsen Welles first film and he wrote it, directed it AND starred in it.
It is the story of a very wealthy man who has everything money can buy, but in the end has nothing.
It starts with him on his death bed and he says the word "Rosebud" just as he takes his last breath.
The rest of the film is a sort of detective story of why his last word was "Rosebud".
The film is loosely based on the life of William Randolph Hirst, a billionaire of the time (still alive then) who was so angry that the film had been made that he offered to buy up all the prints of the film and destroy them.
It is said that "rosebud" was the nickname Randolph Hirst had for his girlfriend's "private parts" which upset him even more.
Here is the opening shot of the movie, moving slowly through Kane's huge estate finishing up as his death bed. See the atmosphere built during these opening 3 minutes
