OK, I'm confused now

Do I understand that there are two movies called The Bermuda Triangle, both of them having a connection to a writer named Charles Berlitz?

On E-bay, I'm seeing lobby cards and press photos for a movie identified as Charles Berlitz's Bermuda Triangle. One of the photos shows a Navy fighter plane crew (who presumably disappeared), as well as a photo of two divers, and one of a radio/radar operator (like from an airport control tower).

Now, I don't recognize any of these from the movie starring John Huston, Andres Garcia, and Hugo Stiglitz. That's not unusual, there's lots of lobby cards and press photos from movies that don't necessarily depict scenes that actually appear in the movie (ask any James Bond fan about that).

But I see the Berlitz name connected with the Huston/Garcia/Stiglitz vehicle, but IMDB also has a listing for another movie with the same name, also with the Berlitz name connected.

So my question is, is IMDB mistaken? I'd hate to go chasing after this other movie, only to find it's the one I've already seen.
