Over the past several years, Alexandre O. Philippe has made quite the name for himself when it comes to documentaries. And now we’ve got word on another hugely intriguing project for the filmmaker.

Announced by Philippe at Sundance this past weekend, it’s been revealed that he’s actually already shot a documentary focussed on The Exorcist. Not just that, but Philippe is working with William Friedkin on the doc.

Speaking to Bloody Disgusting about all of this, Philippe enthused, “So, on The Exorcist, I’m working with William Friedkin. I’ve been working with him now for a year, a little more than a year actually. It’s very different. This is just going to be him and it’s basically about his very personal process. The approach was to do a film on The Exorcist using the Hitchcock/Truffaut model of interviews. I said to him, ‘I just want to sit with you for days and crack open The Exorcist and get into your process as a filmmaker.’ We’ve had four and a half days of interviews. As you can imagine, we went pretty much in depth.”

Of course, The Exorcist has been the focus of countless documentaries over the decades. When asked about how his film will differentiate from those others, Philippe explained, “There’s no talk at all about special effects, about the cinematic tricks. Instead we talked about art. We talked about music, about opera, about movies from Citizen Kane to Ordet by Dreyer, to 2001, The Third Man. It’s a very intimate chamber film about William Friedkin as an artist and his process in the making of The Exorcist.”

To date, Alexandre O. Philippe has wowed with documentaries such as The People vs. George Lucas, Doc of the Dead, 78/52: Hitchcock’s Shower Scene and Memory: The Origins of Alien (which screened at Sundance ahead of a release later this year), and his comic book work over at Fried Comics.

Expect more on this Exorcist doc as we get it.
