Quentin Tarantino's ''best character'' ever written was Hans Landa.

The legendary filmmaker has admitted his favourite fictional person he has invented throughout his career is the main antagonist in his 2009 production 'Inglourious Basterds', and he believes it will be the best protagonist he will ''ever'' write because he is ''linguistic genius''.

Speaking to Esquire.com about the highlights of his long-standing career at the helm of the film industry, he said: ''Landa is the best character I've ever written and maybe the best I ever will write.

''I didn't realize [when I was first writing him] that he was a linguistic genius. He's probably one of the only Nazis in history who could speak perfect Yiddish.''

And the 53-year-old actor has revealed there was a specific criteria to match when he was casting for the role, which saw Christoph Waltz land the part as the sadistic Nazi officer and receive a Oscar for his portrayal in the movie.

He explained previously: ''Actors didn't get my poetry.

''I literally had to consider I might have written an unplayable part.''

Although Quentin admitted he will stop making films after he has met his target of 10 movies, he has teased there may be a comeback many years later.

He said: ''I am planning to stop at 10 [films], but at 75 I might decide I have another story to do.''

Meanwhile, the director has revealed his whole back catalogue of films - which include 'Pulp Fiction', 'Kill Bill' and his latest release 'The Hateful Eight' - all exist in the same universe and share a connection.

Speaking previously, he said: ''There is actually two separate universes. There is the realer than real universe, alright, and all the characters inhabit that one. But then there's this movie universe. So 'From Dusk Till Dawn', 'Kill Bill', they all take place in this special movie universe. So when all the characters of 'Reservoir Dogs' or 'Pulp Fiction', when they go to the movies, 'Kill Bill' is what they go to see.''
