I love the 1974 version. I was never a big Redford fan but thought he made a great Gatsby and I was always a big Bruce Dern fan but thought he was miscast as Tom Buchanan.
Was that Bruce Dern playing Tom? I like Tom in the movie, although I can’t remember if I like him in the book ;-). We have a couple of copies around here somewhere - it’s in my kids’ high school English curriculum, just like it was in mine in 1983.
