I would not call Lawrence of Arabia a biography film since so many liberties are taken (not that they are not taken in nearly all biography films, but Lawrence of Arabia is too inaccurate to be considered a biography). That does not take away from the amazing film it was, it is still one of the greatest movies ever made. Any list of greatest films of all time in which this in not in the top 10 isn't worth that paper it's printed on.
