10 Great Movies Everybody HATED Making

The enormous amount of work that goes into making even a terrible film is undeniable: any completed movie is the result of hundreds of cast and crew members pooling their talents to try and create something worthwhile.

But truly great films are often only achieved through tremendous adversity, enough that those who worked on them - both in front of and behind the camera - had an absolutely miserable time.

From technically complex productions that drove the cast absolutely mad, to location shoots where everything possible went totally wrong, and directors whose filmmaking styles pushed the cast and crew to the brink, these 10 films left all involved with some major battle scars.

And yet, for the majority of these movies you'd never guess they were forged through such intense circumstances: the precision of the filmmaking and the brilliance of the performances suggest not even a hint of major behind-the-scenes headaches.

While those involved might be able to look back fondly upon these movies in retrospect, especially given how beloved they now are, at the time making these films was absolute hell...

Alfonso Cuarón's 2013 sci-fi masterpiece Gravity is an incredible feat of effects-driven filmmaking.

Cuarón originally planned to complete the project within a year, but due to the mind-boggling complexity of the VFX it ended up taking almost five years of his working life, while the shoot itself required absolute precision from its cast and crew.

Case in point, Robert Downey Jr. was originally signed to star as astronaut Matt Kowalski - a role eventually played by George Clooney - but bailed after it became clear that his improvisational acting style clashed with the strict requirements of such a carefully controlled project.

The experience for stars Clooney and Sandra Bullock was uncomfortable, to say the least. With most of the film's imagery being computer-generated, the actors spent up to 10 hours a day inside a 9x9-foot mechanical rig intended to simulate a space shuttle, while being directed by Cuarón via earpiece.

Bullock said of the harrowing experience:

"It was just frustrating, painful and isolating... I wanted to kill [producer David Heyman] and Alfonso regularly. So all of your hate, and your anger and your rage, you just give forth in your work and hope it translates onscreen."

Ultimately Gravity went on to win seven Oscars, including Best Director, and grossed over $700 million worldwide.

Given that Bullock managed to secure a mind-boggling 15% share of the movie's first-dollar box office grosses in addition to her $20 million salary - not to forget a Best Actress Oscar nomination to boot - she's probably happy with how it all turned out.
