Even IMDb is in on it...
Go the search-field on top of the page, type in "Bananas", and you won't get a match for the documentary "Bananas!*" (although this docu and the W. Allen movie).
Even if you try "see all results".
So...what other reason could be that it has been removed as a doable search on this page?
Yes, "Bananas!*" has a page like any other movie here on IMDb, BUT its not searchable; I found through a link in the "Movie connections" to this movie.
Very disappointing IMDb.
Shoot straight, you bastards - don't make a mess of it!
