7) Avatar (2008)
Avatar, another James Cameron movie, was a popular and an award-winning movie. The movie was delayed until movie making was technologically advanced enough for it to be made. The movie, on release, did extremely well, being the first movie ever made to crack 2 billion dollars at the Box office (3.020 Billion dollars to date).
But again, adjusting for inflation, gone with the wind movie still remains a contender for the title.
