The Light at the Edge of the World
I see I missed "But Not for Me" (well, unless one could identify Clark Gable as an "ape!" LOL)
Edge of Darkness
(They were posted simultaneously, but actually feolala must have been seconds ahead -- happened before but I guess we have to go on!)
BTW, I know I've been kind nitpicky before about using links that don't follow the rules. Linking a film because of the same actor doesn't exactly match what feolala had in mind. It's either a word (including a synonym) or a concept.
The Ghost and the Darkness
Clark Gable is an APE? Well okay, he-man, ape-man, what the heck! (Agree on the actor-link rule.)
The Ghost and Mrs. Muir
(I guess it's more fun to guess than to offer the reason for the link? LOL)
Sure! I like to leave 'em guessing! (But then I'm always embarrased when I have to ask! (Which is often!

)
I would think everyone would have picked up on Muir!)
