Quentin Tarantino has been sued by a father and son writing duo who accused him of copyright infringement over his hit 2012 movie Django Unchained.

The 52-year-old filmmaker was named as a defendant along with The Weinstein Company and Columbia Pictures, according to an article on Wednesday by Variety.

The lawsuit was filed on December 24 in federal court in Washington DC by Oscar Colvin, Jr., and his son Torrance J. Colvin.

The Colvins allege the defendants infringed on their screenplay Freedom and cited what they claimed were extensive similarites to Tarantino's script.

Tarantino wrote the screenplay and directed Django Unchained and it became his highest-grossing film with more than $425 million at the worldwide box office.

He also won an Academy Award, BAFTA award and Golden Globe award for writing the screenplay.

The film starred Jamie Foxx as the titular Django Freeman along with Oscar-winner Christoph Waltz, Leonardo DiCaprio, Kerry Washington and Samuel L. Jackson.

The lawsuit claimed the Colvins registered Freedom in 2004 with the Writers Guild Of America.

The Freedom script also was taken to the CAA and William Morris Agency and posted on the now defunct Trigger Street Labs script review website, according to the lawsuit.

The lawsuit presented alleged extensive similarities between the Freedom script and Django Unchained.

'Before Django Freeman, there was an escaped slave named Jackson Freeman who desired to purchase his family’s freedom from a malevolent plantation owner,' the lawsuit said.

The lawsuit also alleged: 'Defendant Tarantino claims to have based his screenplay on Sergio Corbucci's Django, but the truth is that there are far more similarities between Freedom and Django Unchained than between Django and Django Unchained.'

The plaintiffs also asserted that a key plot point in which Django returns to free his wife [Washington] from her plantation owners [DiCaprio] was lifted from Freedom.

'Returning to the hellish realm of the South to purchase the freedom of his loved one(s) with the assistance of a Caucasian in the South is the uniquely original beat that links Django Unchained to Freedom,' the lawsuit stated.

The lawsuit was seeking compensatory damages of more than 'hundreds of millions of dollars'.

Tarantino's latest move The Hateful Eight was released by The Weinstein Company on December 25.
