Musicals (ones that could be vastly improved on film):
A Chorus Line
The Wiz
Man of La Mancha
Brigadoon
Guys and Dolls
Carousel
A Little Night Music
Non-musicals (not necessarily because they were rotten the first time, but because they could be given a newer, stronger approach):
Agnes of God
The Beast With Five Fingers
Band of Angels
You Can't Take It With You
The Great Gatsby
The Children's Hour
The People (TV movie)
Blithe Spirit
'Night Mother
A Doll's House
Three Sisters
Musicals and plays that I think should be made first, before any of these remakes:
Fences
Sunday in the Park With George
Big River
Ragtime
Precious Sons
Into the Woods
Once On This Island
Jelly's Last Jam
Kiss of the Spider Woman
The Most Happy Fella
