'The Exorcist' director has branded its sequel a "f***ing disgrace".
Filmmaker William Friedkin - who was at the helm for the original horror classic in 1973 - didn't return for the sequel four years later and he has now insisted it's the worst film he has "ever seen".
Speaking on the 'Movies that Made Me' podcast, he ranted: "I tell you, I did see a great deal of 'Exorcist II', under the following circumstances. I was at the Technicolor lab, color timing something, and one of the timers said, 'We just finished Exorcist II, would you like to have a look at it?'
"And I don't know why, but I went into the room and I sat through maybe 40 minutes of it. It's the worst piece of s**t I've ever seen. It's a f***ing disgrace.
While Friedkin praised the cast - which saw the likes of Linda Blair and Max von Sydow reprise their roles as Regan MacNeil and Father Merrin from the original - he felt the second film disrespected William Blatty, who penned the novel used as source material for the big screen adaptation.
He added: "And God, what a cast it had --- Richard Burton, and Max von Sydow, and Louise Fletcher, plus Linda Blair. James Earl Jones.
"That's the worst 40 minutes of film I have ever seen, really, and that's saying a lot."
'The Exorcist II' had Academy Award nominee John Boorman at the helm alongside its stellar cast.
However, scriptwriter William Goodhart had only penned one movie before working on the sequel - and only wrote one afterwards.
Despite being panned by critics at the time - and since - it was followed by 'The Exorcist III' in 1990, while 'The Exorcist: The Beginning' (2004) and 'Dominion: Prequel to the Exorcist' (2005) were all made to continue the franchise.
