Tom Hanks -

In 2000, we saw the actor play a survivor in a desolated island in 'Cast Away.' Tom Hanks actually sustained an injury that would have been fatal if he really were alone on that island.

Ashton Kutcher -

Things went terribly wrong for the actor when he changed his diet to play Steve Jobs in the 2013 biopic 'Jobs.' Kutcher delved into fruitarianism, which was essentially a fruit-based diet that Jobs himself had tried. Except, it didn't work for the actor.

Ashton Kutcher -

"I ended up in the hospital two days before we started shooting the movie. I was doubled over in pain, and my pancreas levels were completely out of whack, which was terrifying, considering everything," said Kutcher.

Harrison Ford -

The gun versus sword scene in 'Indiana Jones and the Raiders of the Lost Ark' (1981) became a classic. But actually, this was supposed to be an epic sword versus whip fight instead. The reason why the scene was so simple was because Ford was really ill with diarrhea!

Harrison Ford -

"It was meant to be the ultimate duel between sword and whip. I was suffering from dysentery, really, found it inconvenient to be out of my trailer for more than 10 minutes at a time," explained Ford.

Emma Watson -

Darren Aronofsky—the director of 'Noah' (2014)—certainly had good intentions in making the movie set environmentally friendly. This meant that plastic water bottles were a no-no. This had disastrous consequences for Emma Watson.

Emma Watson -

"Having no water bottles on set at five in the morning, when you're exhausted and delirious, wasn't ideal. I was so tired one morning I picked up a mug from my trailer and drank some stagnant water that had been there for the duration–so three months. I was so ill," confessed Watson.

Jonah Hill -

Coke consumption was abundant in 'The Wolf of Wall Street' (2013), so the actor had to snort vitamin powder in many scenes. The powder was safe...if done in small quantities, which was obviously not the case.

Jonah Hill -

"I had to be hospitalized. If you ingest that much matter into your lungs you’ll get very sick, and we were literally doing fake coke for, like, seven months, every day," said Hill.

Leonardo DiCaprio -

If you've ever watched 'The Revenant' (2015), it's easy to imagine how hard it was for the whole film crew to shoot in those weather conditions.

Leonardo DiCaprio -

Not only that, but Leonardo DiCaprio was actually sick on camera, when he bit into a raw bison liver. It proved to be too much for DiCaprio, who happens to be vegetarian. He did win an Oscar for his performance, so maybe it was worth it!

Daniel Day-Lewis -

The actor played William "Bill the Butcher" Cutting in Martin Scorsese's 'Gangs of New York' (2002). Being a method actor, Day-Lewis walked around in freezing temperatures with his costume on.

Daniel Day-Lewis -

The actor came down with pneumonia as a result. "I had to do my preparation. I will admit that I went mad, totally mad… He was a bit of a punk, a marvelous character and a joy to be–but not so good for my physical or mental health," said Day-Lewis.

John Rhys-Davies -

It wasn't easy for the actor to change his facial appearance to play Gimli the Dwarf in 'The Lord of the Rings' movies.

John Rhys-Davies -

The prosthetics on his face contained latex, and it happens that Rhys-Davies is allergic to it! Needless to say, the actor didn't like to walk around with a skin rash and his eyes swollen.

The late actor headed to the Amazon jungle to film 'Fitzcarraldo' (1982). Robards had already shot almost half of the movie, when he came down with dysentery. He had to leave the location to be treated and was unable to return. Director Werner Herzog had to recast and shoot everything all over again.

"It was a hardship condition-right in the jungle, on the Amazon River bank… It was unhygienic. The place was rife with insects and mosquitoes,'' said Robards' agent, Clifford Stevens.
