Here's a fun episode of TV's Password that aired in 1967, with guest stars Joan Fontaine and her Gunga Din co-star Douglas Fairbanks, Jr. When Joan is introduced by host Allen Ludden, I think she says, "How's Betty?" referring to Ludden's wife Betty White
In the beginning part of this clip, Joan mentions she will be performing in "Dial M For Murder" at the Ivanhoe Theater in Chicago (postcard of the theater building below)
The theater building still stands (It still looks like a castle) but it is now a Binny's liquor store.
Here are some pics of how it looks today:
