There's so much that goes into the creation of a movie - writing, direction, acting, production design, visual effects, sound design, and so on - that neither success nor failure are ever really the result of a single person's efforts.
That said, the buck understandably stops with the director, who while overseeing shooting is primarily responsible for delivering the final film, no matter how much producers might end up meddling in it.
Directors can understandably be more than a little sensitive about how their films are received - after all, a bad movie is a poor reflection on them as an artist - but sometimes filmmakers have enough humility to accept when something just doesn't pan out.
These 10 directors, some among the most famous to ever get behind the camera, have all spoken candidly about how one of their movies just didn't work, whether they knew it before the cameras started rolling or not.
Years after the fact, after they've moved on to other projects, these filmmakers keenly accepted that one of their films failed in its intent, while also making an effort to explain why it happened...
10. Sam Raimi - Spider-Man 3
You have to feel for Sam Raimi during the making of Spider-Man 3. It's well known that producer Avi Arad forced him to include Venom (Topher Grace) in the film against his wishes, and it's painfully clear throughout that the director's heart just wasn't in it.
Despite mixed reviews, Spider-Man 3 was a massive commercial success, yet in recent years Raimi has held nothing back in admitting that it categorically didn't work. In a 2015 interview on the Nerdist podcast, Raimi not only called Spider-Man 3 "awful," but explained why:
"I messed up plenty with the third Spider-Man, so people hated me for years - they still hate me for it. It's a movie that just didn't work very well. I tried to make it work, but I didn't really believe in all the characters, so that couldn't be hidden from people who loved Spider-Man. If the director doesn't love something, it's wrong of them to make it when so many other people love it."
Raimi expanded that the producers' focus was on outdoing the first two films while he "didn't really have creative control," as is evident when you compare its quality to that of the first two Spider-Man movies.
After negotiations for Spider-Man 4 fell through, Raimi steered clear of superhero movies for an entire 15 years, until he returned for the recent Doctor Strange in the Multiverse of Madness, which was itself rather polarising with audiences.
