The following page appears to be fake, Untitled Betty Boop
. The IMDB link goes nowhere and there does not appear to be an untitled Betty Boop movie on IMDB if you do a quick search. Also, most of the uploads appear to be either pre-production are from older BB cartoons, promotional art that was intended solely for sale and not connected to any specific movie or short and the rest is just fan art. Please double check me here but it seems this entry may need to be deleted or at least looked into a bit.
