His remake is alleged to have been plagiarized.

Quentin Tarantino has been sued by two scriptwriters who allege that his 2012 film Django Unchained infringes the copyright of their screenplay.
The lawsuit filed by Oscar Colvin, Jr. and his son Torrance J. Colvin claims that Tarantino’s movie closely resembles the script of their film Freedom.
The writer’s say they submitted their screenplay to the William Morris Agency, which suggested Tarantino as a possible collaborator.
In the suit, the Colvins allege that they “provided the heart, bones and muscles to develop the unique idea that eventually would be transformed into Django Unchained … Tarantino took the plotlines and main story of Freedom and Tarantino-ised them.”
They continue: “Before Django Freeman, there was an escaped slave named Jackson Freeman who desired to purchase his family’s freedom from a malevolent plantation owner. Before Dr Schultz, there was Samson, another white man, who would assist Mr Freeman in his efforts to rescue his loved one(s) from slavery.”
