How do you quantify that?
Exactly!?! This film still sells out in L.A., fills theatres and special events anywhere it's screened and the recent TCM screening at the Chinese was packed. It still sells tons of merchandising. So somebody's still giving it word of mouth.
It's never been a "Sight and Sound" film. Never a film scholar's darling. It incites more discussion and opinion, though, than "Citizen Kane" or "Casablanca" or more benignly lovable classics due to its political views and setting.
But its popularity with the people is still immense. The book that was released in November on Vivien Leigh is in second printing and the BFI tribute to her a smashing success. It's last theatrical release did better than "The Godfather"'s restoration and subsequent theatrical release. So I'm curious in what respect its rep has diminished. WB apparently hasn't started thinking so and stopped pushing new editions in our faces.
P.S. The digital transfer at the Chinese seems to be the same they have been showing since 2009. It is unlikely the BFI showed a different master. If anything needs to be done to the transfer at all, it might be to take out the jaundiced look to the skin tones.
