The director asked the acclaimed composer to come up with a score for his latest film, but Morricone was busy working on other projects.

Morricone instead offered him the soundtrack he composed for John Carpenter's 1982 classic The Thing which did not make the final cut.

"I had a little voice in my head saying, 'This material (The Hateful Eight) deserved an original score.' And I've never thought that way before, I've never had that voice before. I didn't ever want to trust a composer with the soul of my movie," Tarantino revealed during a question-and-answer session hosted by Interstellar director Christopher Nolan in Los Angeles.

"And he's (Morricone is) like, 'This is not going to work. I'm working with (Italian director) Giuseppe Tornatore, and he just finished shooting the other day, and I've got to do his score, this is not going to work. I was told a lot of things that weren't correct, and I'm really sorry.'"

Tarantino goes on to explain that Morricone offered him The Thing music instead: "(Morricone said) 'I wrote a whole orchestra score (for The Thing), and I wrote a whole synthesizer score, because I knew that was what (John Carpenter) was used to, and I gave him everything, and the only thing he used in the entire movie was the synthesizer main title (track)'... So, he (Morricone) goes, 'What I can do is I'll write the theme... and with the other Thing pieces of music, now you have your original score that's never been used in a movie before.'"

The Thing star Kurt Russell also leads the cast of The Hateful Eight.
