Eh, top-20 grossing only and starts in the early 80s. There are lots of remakes and sequels (and some "cinematic universes"!) in the 1900-1950 range—not infrequently, one of the remakes is far better-known or better-regarded now than the original.
[EDIT] I've actually looked into this before and if you have better data on it I'd genuinely love to see it—I couldn't find any.
[EDIT EDIT] What I was most interested in was seeing whether there was a major change in this in the 60s-80s when director-as-auteur trend took over after the Studio System was broken up—arguably we're kinda trending back toward a Studio System sort of arrangement, so it'd be interesting to see if a ~century-long graph that includes wider-ranging data looks U-shaped.
