Tarantino's film has come under fire for its controversial content including violence, strong language and the sensitive subject of slavery.
> Digital Spy's 'Django Unchained' review: Quentin Tarantino is a director off the leash
Fuqua spoke out in support of Tarantino on Sunday (December 30) during an appearance at the Hollywood Film Festival in Capri, Italy.
The Training Day director addressed the recent comments made by many when it came to Tarantino's use of the "N"-word and Spike Lee's recent statement that the movie was "disrespectful".
Do the Right Thing and Inside Man filmmaker Lee also said that he has no interest in seeing Django Unchained, and alleged on Twitter that the movie trivialises the treatment of African-American slaves.

Fuqua director also said of Lee's public criticism of Tarantino: "That's just not the way you do things. If you disagree with the way a colleague did something, call him up, invite him out for a coffee, talk about it. But don't do it publicly."
Django Unchained is out now in the US, and will open on January 18, 2013 in the UK. The film stars Leonardo DiCaprio alongside Foxx, Christoph Waltz, Samuel L Jackson and Kerry Washington.
