Revered Italian composer Ennio Morricone has vowed never to work with Quentin Tarantino again, because he didn't like the way his music was used in Django Unchained.

The 84-year-old maestro has worked with the filmmaker on four projects, but has slammed Tarantino for using music "without coherence".

The man behind classic Spaghetti Western film themes including The Good The Bad and the Ugly and A Fistful of Dollars gave Tarantino permission to use his Ancora Qui in Django Unchained, alongside three instrumental pieces. The two film icons also worked together on Inglourious Basterds and the two Kill Bill films.

But, speaking to students at Rome's LUISS University earlier this week (begs11Mar13), Morricone said, "I wouldn't like to work with him again, on anything. He said last year (12) he wanted to work with me again ever since Inglourious Basterds, but I told him I couldn't, because he didn't give me enough time. So he just used a song I had written previously."

Explaining the reason behind his Tarantino boycott, the composer added, "He places music in his films without coherence... and you can't do anything with someone like that."

And Morricone admits he wasn't a fan of Django Unchained: "I didn't care for it, too much blood."
