Jane Wyman passed away this Monday. She was 93. She was an Oscar-award winning actress and appeared in films including The Glass Menagerie and Pollyanna. She had her own television show at one time and also starred as Angela Channing in Falcon Crest.
Dunno if GSN would do a tribute or anything, but if they did, I checked and she did appear once on What's My Line? She was the mystery challenger on EPISODE #515, to promote Pollyanna. Dunno exactly when this episode last aired on GSN, but definitely sometime within the last couple of years because I see a note of my own there. One of the notes for this episode describes its entertainment value as "high."
