It's about 3 hours iirc.. If somehow you can get an updated blu-ray version I would think it would be worthwhile.
When I watched it a long time ago on vhs afterwards I considered it to be up there with films like The Deer Hunter and Taxi Driver...not quite as good.
Hugo is an underrated Scorcese film, I thought it was exemplary.
I think there might be a few versions of Once Upon a Time in America. The version I have is 3:49 long. Apparently there's an extended directors cut that's 4:11 long and there's a re-cut that is 2:19. I've never seen any version. I think the 3:49 is the most common.
It's on my "Movies to watch" list, but so are about a hundred other films.
