I think Ian's hit it... it is toward the very end of the film, as I recall (it's been a looong time since I've seen
Torn Curtain), as they've made their escape; they end up having swum to shore and sitting wrapped in blankets drying off.... (Knew the scene rang a bell, but couldn't quite place it, or see the faces.....)
Incidentally, that was not the original of The Cat and the Canary. That film had several remakes, all of which blent horror and humor:

It was originally stage play, as I recall. I've not seen the 1921 version (the genuine original) but I have seen the 1927 film... quite fun, and some of the shots in there are still being imitated to this day (including one in, appropriately, Dead Silence: the corridor with the curtains blowing). It has some genuinely eerie moments, that silent film, and influenced James Whale, who was a great fan of Paul Leni, from what I understand....
