Talk to Dom, he's a major JB fan.
I have some very old, obscure JB movies that I taped off TCM. if you want them copied for screen grabs let me know.
Disraeli(1929)
Vouges of 1938(1937)
Moby Dick(1930)
Secret Beyond the Door(1948)
also one other from 1947, a fim noir directed by Jean Renoir. can't recall the title, will look in my collection to check. Most of it's on a beach.
I also have her last ever interview, from the 1980s, on The Joe Franklin Show, and Scarlet Street, but that's readily available.
