Harry Styles is already taking his new career path extremely seriously, as it's reported he's off to sea in prep for his forthcoming movie debut.

As in where there are sharks and real life potential danger.

The 1D singer is reported to be joiningthe rest of the cast and crew of Dunkirk on an old Navy ship, where there won't even be access to running water or electricity as they get in character for filming.

A source told The Sun: "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."

Seeing as the film is based on the events that took place in Dunkirk in June, 1940, maybe it's a good idea he waved goodbye to Instagram for a few weeks.

But comes back safe and sound, obvs.
