London: Leonardo DiCaprio was close to mental meltdown while on the set of ‘Shutter Island’.
On-set consultant Dr James Gilligan, who worked with DiCaprio, 35, during the entire shoot, feared for the ‘Titanic’ star as he fought to get to grips with his character.
And we discovered that DiCaprio, who played US Marshal Teddy Daniels, was not his usual cool self during the shooting of the film.
The film was shot at the eerie, abandoned mental hospital where the film was shot in Boston, Massachusetts.
The box-office hit shows his character investigating weird goings-on at the psychiatric clinic.
According to Gilligan, DiCaprio descended into the kind of nervous state witnessed in real mental health patients.
“You could see the level of tension building up in him. He constantly tried to avoid being taken over by his character,” the Daily Star quoted him as saying.
DiCaprio even admitted he was emotionally moved by the movie.
He revealed: “This was a very tough film to make for sure, both emotionally and physically. It was among one of the harder ones I’ve done.”
Before filming, DiCaprio was shown a documentary about the mistreatment of patients in the 1950s – when the film is set – showing electric shock therapies and lobotomies.
The star researched the role in such detail he even studied an official mental health doctors’ training video on the Internet.
He read up on how different treatments affect patients, how they act and what they look like.
Dr Gilligan said: “DiCaprio wanted to get in the skin of Teddy – learning the character’s conditions in detail – which he did successfully.”
