23. THE GRAPES OF WRATH (1940)
24. E.T. THE EXTRA-TERRESTRIAL (1982)
25. TO KILL A MOCKINGBIRD (1962)
Only four of the IMDB top 25 make the cut. #1 Shawshank comes in at #72 on the AFI list.
I have not seen 11, 12 or 18.
ETA: That list was compiled in 2007, the 10th anniversary of the original list.
There's a huge generational gap between the IMDB and the AFI lists. On IMDB there are only four films from before 1972; on the AFI only five films after.
