Dark Passage - Paita, Peru
Parry arranges to meet Irene in Paita, a coastal resort in Peru. Set in a natural bay secluded by high cliffs, Paita is a beautiful town with a rich swashbuckling history. Over the centuries conquistadors, pirates and buccaneers have all left their mark there.
But this final scene, pure Hollywood schmaltz with crashing waves and festive music, was most likely filmed in the Warner Brothers studios in Burbank, California. No dialog, just a 'happily ever after' reunion to give everybody the warm and fuzzies as they make their way home from the theater.
Parry anxiously waits at his table alongside a crowded dance floor ...
... He spots Irene (the waves behind him are clearly a rear projection) ...
... and Irene spots Parry ...
... and presumably they live happily ever after!
