I actually haven't seen this classic either sadly. So many of the classics that come on TV I don't watch because of edited content and because I have to catch it before it starts. I want to see it start to finish.
Also haven't seen Shindler's List.
Wait wait wait....wait.....wait....
You haven't seen The Shawshank Redemption? That's like the best movie ever made. I didn't mention it because I figured you'd have seen that one.
Go watch that one immediately, then watch Harry Potter from start to finish.
