Three old classics and a more recent classic :-D :-X
I was reading about the making of Cleopatra just recently. There was way more drama just getting the film made than there was on the screen :-() It almost sent 20th Century Fox broke and took about three years to make - not so much because it was a difficult movie to make but because of all the cock-ups and re-shoots (a good deal of the movie had to be in effect shot twice).
Here's some info:
