I almost nominated Seven Samurai, but decided it may have been too long to watch for everyone.
HOF rules state nominations cannot exceed 220 minutes.
Seven Samurai's runtime, as listed on IMDb, falls at 207 minutes so it's pushing the limits but would still qualify.
I won the 13th HOF with
Dances With Wolves. The theatrical cut of that is 3 hours long, but at least one participant watched the 4 hour extended cut, which even I haven't seen. I think if the movie is good enough, then the length won't hinder it too much.
Incidentally I watched
Seven Samurai for the 50s countdown. I rated it a
- and had it at #11 on my countdown ballot. I don't love it but I think it might do well in a HOF.
