While many have read the book, I think pretty much everyone has seen both movies for the most part. The two are a bit different. The "remake" was ironically closer to the novel, but I just prefer the original with Gene Wilder.
While the author Roald Dahl hated it, I think it's a masterpiece. Remains one of my favorite films ever. I thought the newer Willy Wonka was good, but it just isn't in the same class as the first.
Which do you prefer?
