It's not exactly uncommon to hear of a big-screen thespian feeling a bout of instant regret upon finally wrapping on a wholly disastrous filming experience, with most humble actors being quick to admit that not every film they've ever been attached to has been an all-round success by any means.
However, in some cases, movies that have gone on to become some of the most cherished and celebrated projects of their time have still managed to leave some eye-catching names wishing they'd done things differently, or even never been exposed to the finished well-known flick in the first place.
It isn't just those who found themselves in the fan-favourite feature themselves who have gone out of their way to throw shade at the production and finished article either, with some stars from outside of the cast and crew of a project also being all too happy to bury a big-screen experience many hold dear to their hearts.
From everyone's favourite wizard finding it tough to take in one of his most challenging adventures, to some stars completely slamming some of the most acclaimed performances of all time, these actors aren't a fan of the movies that many would class as some of their most treasured slices of cinematic goodness.
10. Robert Duvall Didn't Like Stanley Kubrick's Work - The Shining & A Clockwork Orange
Without a doubt sitting as two of the most influential and unsettling features ever thrown into the big-screen landscape, Stanley Kubrick's The Shining and A Clockwork Orange have both terrified and inspired generations in the wake of their 1980 and 1971 releases, respectively.
One person who most definitely wasn't impressed by the shifts put in by the likes of Jack Nicholson and Malcolm McDowell, however, comes in the form of The Godfather icon Robert Duvall. As the respected screen veteran confessed in a THR Roundtable conversation a few years back, while Duvall still classed both as "great movies", they contained "terrible performances" by those being housed within the features.
This was on the back of branding "the great Stanley Kubrick" as "an actor's enemy" as well, with the star also twisting the knife further by explaining, "How does he know the different between the first take and the seventieth take? I mean, what is that about?"
Never one to keep his opinions to himself, Duvall clearly had no time for Nicholson huffing and puffing and blowing a house in during the likes of said Shining.
