A long time ago - perhaps around the time I started the Louise Brooks Society back in 1995 - I had the chance to see Francis Lederer at a Cinecon film convention in Hollywood. Lederer played Alwa - Brooks' love interest, or at least one of them, in Pandora's Box. He was rather elderly then, but spoke after a screening and took questions from the audience. I really didn't have a chance to meet him, but did get his autograph in the convention program! Somewhere, I have a snapshot Lederer and myself.
The Guardian article also notes: "Among the other juvenile survivors are June Havoc, Virginia Davis (who took the lead in Walt Disney's Alice in Cartoonland series), future cinematographer Jack Cardiff and Helen Alice Myres and Diana Serra Cary, who were respectively better known as Baby Marie and Baby Peggy." In the past, I also had the chance to meet two of the stars mentioned, Virginia Davis and Diana Serra Cary (aka Baby Peggy).
