I have not seen the film. I know it has the famouse line"Frankly, my dear, I don't..."
It is a classic film. The movie is based off a novel written by Margaret Mitchell in 1936. 
I'm not much into the older classics biut have seen Wonderful Life, and some hitchcock movie from the 50s and 60s.
Alfred Hitchcock is known as one of the most influential filmmakers of all time. Which was your favorite Hitchcock movie?
Family Plot. A close second is North by Northwest.
Family plot was the final film directed by Hitchcock. I have not seen it, but I am interested now.
