The helmer also hinted at a third part in the unofficial trilogy during a recent interview with Total Film.
"Inglourious Basterds and Django Unchained bespeak a trilogy," Tarantino revealed.
"As different as they are, there is a companion-piece quality. There might very well be a third one. I just don't know what it is yet."
2009 adventure drama Inglourious Basterds chronicled a group of Jewish American soldiers' fictional plan to assassinate Nazi leaders.
Christoph Waltz won an Oscar for his turn as ruthless, charismatic SS officer Hans Landa in Inglourious Basterds, and is also a co-star in Django Unchained as a former dentist who joins Foxx's Django on his journey.
