Yep. But Miss Monroe had already died at that point and “Niagara” was a 20th Century-Fox film. It made perfect economic sense for both EON and UA to plug “Call Me Bwana” instead. I’m guessing more people have either seen or tried to see the 1963 Bob Hope comedy for the reason it was in FRWL alone.
I’ve only seen “Bwana” just the one time, probably 20 years or so ago. It was certainly nowhere as good as FRWL. Then, of course, when you go to see a Bob Hope movie, it’s just Bob Hope being Bob Hope. I wonder why Anita Ekberg never made an appearance in a Bond film.
