One thing about RKO, they never give you a dull ending.
Whether it's King Kong's last stand atop the Empire State Building, the revelation behind Citizen Kane's last words, or the climactic struggle between the British Army and the Thuggee, RKO studios sure knew how to give a climactic ending. I love the trivia about how they added the battle after the original ending was deemed too dull.
"You know, I like the emotional ending with Gunga Din's eulogy, but... It's a little anticlimactic. You think maybe we could add a scene with 600 extras going at it in armed combat?"
"Sure, sounds great."
It's such a pity that they're no longer around, save for when a remake (The Cat People, Mighty Joe Young) is needed.
