Thom Yorke has compared composing the 'Suspiria' soundtrack to casting spells.

The Radiohead frontman has taken on his first feature film score for Luca Guadagnino's remake of Dario Argento's 1977 film and said the entire process was magical.

He told The Hollywood Reporter: ''I kept thinking to myself that it's a form of making spells.''

''So when I was working in my studio I was making spells. I know it sounds really stupid, but that's how I was thinking about it. It was a sort of freedom I've not had before. I've not worked in the format of song arrangement. I'm just exploring.''

''I'm putting things out into my studio and seeing what my studio is bringing back. It was a sort of maybe a beginning launch of an idea. It was just a really cool way to totally immerse myself in an area I wouldn't normally go with full permission.''

Thom, 49, also admitted he was initially hesitant to take part because he feared he could not match the original soundtrack by Goblin.

He said: ''I referred to the original 'Suspiria' film. It was an odd process from the beginning. When they first came to see me, the producers and [editor] Walter [Fasano], I just thought they were mad, because I've never done a soundtrack before, And 'Suspiria' is one of those legendary soundtracks. It took a few months to even contemplate the idea.

''It was one of those moments in your life where you want to run away but you know you'll regret it if you do. I watched the original film several times, and I loved it because it was of that time, an incredibly intense soundtrack. Obviously Goblin and Dario worked incredibly closely when they did it together.''
