Alright, so you might be familiar with the term "method acting" — a technique that encourages actors to use their own experiences and emotions for roles. This can also involve trying to live as the character — even when the cameras are off.
Of course, this approach — or pursuit of it — can mean that some people take things a bit, er, far. Here are just some actors who really went off the deep end:
1.Lady Gaga spoke in an Italian accent for nine months while filming House of Gucci.
2.Ashton Kutcher was hospitalized twice with pancreatitis while preparing to play Steve Jobs in Jobs.
3.Michael B. Jordan needed therapy after isolating himself while playing Killmonger in Black Panther.
4.Jared Leto sent his fellow cast a dead pig during his time as the Joker in Suicide Squad.
5.Robert Pattinson would try to make himself throw up, lick mud, piss himself, put stones in his shoes, and get drunk during filming of The Lighthouse.
6.Daniel Day-Lewis refused to leave his wheelchair and damaged two ribs while filming My Left Foot.
7.Halle Berry tried out method acting when she didn't shower for 10 days to play a crack addict in Jungle Fever.
8.Jamie Dornan straight-up stalked a woman, leaving the London Underground to prepare for his part as a serial killer in The Fall.
