The One Direction star is set to join the rest of the cast and crew of 'Dunkirk' on an old Navy ship, where there is no access to any electricity or running water.
A source told The Sun newspaper: "Harry is used to living the life of luxury so this will be a very interesting experience.
"He knows this boot camp at sea is a big part of the job and is keen to get stuck in. But this will be tough and producers are trying to make life on board as realistic as possible."
They will have to struggle on with only rations of food and no mobile phones or connections to the outside world.
Producers are hoping the experience will improve the cast's understanding of the plight of the Allied forces on the beaches of Dunkirk, France, in June 1940.
Meanwhile, the 22-year-old singer is keen to focus on both his music and acting going into the future.
Of the film role, an insider said previously: "Harry has gone straight in at the top. 'Dunkirk' will be massive. He was asked to audition for the part - which will be substantial - and impressed Christopher.
"This is now a great chance for him to show his acting skills and put himself in the frame for more huge movie roles. But music is still very much on his agenda and he would like to do both going forward."
