I think we have most listed on Django topic's first two pages:
There are loads of Django films depending how you count 'em. Many many films were re-titled as Djangos in Germany or France or wherever even though they didn't have anything to do with original Django.
Viva Django / Preperati la bara is the most important Django film to me (after the original of course). It's much more better than Django Strikes Again and has more common to original Django than the Rambo-wanna-be from 80's.
