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.
Copyright: SonyTarantino's upcoming Django Unchained stars Jamie Foxx as a slave-turned-bounty-hunter who sets out to save his wife (Kerry Washington) from a vicious slave trader (Leonardo DiCaprio).
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.
