Jonah Hill looks unrecognisable with long blonde hair and a beard for new movie role

I imagine that one of the toughest parts of being an actor is the dramatic changes you have to make to your appearance. Plenty of actors do it, from Christian Bale in The Machinist to Tom Hardy in The Dark Knight Rises - some actors have to put their bodies through hell in order to get into character.

One actor who seems to undergo dramatic weight-loss and weight gains is Jonah Hill. Hill, who is known for his roles in films such as Superbad and The Wolf of Wall Street has continuously battled with his weight, leading to him regularly fluctuating between being super skinny and carrying a few extra pounds.

However, not only has Jonah lost a lot of weight for his latest role, he has also completely transformed his entire appearance. The actor stars in the new movie, 'Don't Worry, He Won't Get Far On Foot', alongside Joaquin Phoenix, Rooney Mara and Jack Black, looking unrecognisable from the Jonah we are used to seeing on red carpets and on our TV screens.

The film is a biopic about the dark-humoured cartoonish John Callahan. Jonah plays that character of Donnie and looks more like Kurt Cobain than the chubby, curly-haired teenager we saw in Superbad.

Sporting long blonde hair, a big beard and wearing checked shirts, Twitter users have lost their collective mind and the actor's new looks, with plenty of them drawing the comparison to the late Nirvana frontman.

The movie is based on the autobiography of John Callahan, which is also titled: Don't Worry, He Won't Get Far On Foot. The biopic will follow the life of Callahan, an alcoholic who becomes paralysed after having a car accident and his emotional journey to solace through drawing. Donnie (Jonah's character), is a spiritual and flamboyant man who serves to remind Callahan to just 'drink water'.

However, while the film has been greeted with generally positive reviews at the Sundance festival, some people are not happy with the casting of Joaquin Phoenix as Callahan. The Ruderman Family Foundation, a foundation that campaigns for the inclusion of disabled people in society, said that they think that the casting was a 'mistake' and that it was 'unacceptable and offensive'.

In a statement issued by President Jay Ruderman, the foundation said:

"It was a mistake for director Gus Van Sant to cast Joaquin Phoenix in his upcoming biopic about disabled cartoonist John Callahan. The time has come for the entertainment industry to audition and cast actors with disabilities to play leading roles portraying disability.

As we enter 2018, American society no longer finds it acceptable for white actors to play Black, Asian, or Hispanic characters. It is equally unacceptable and offensive for able-bodied actors to be cast inauthentically in the roles of characters with disabilities."

'Don't Worry, He Won't Get Far On Foot' is out in cinemas in May 2018 and will no doubt cause a stir for both its casting, and the transformation that Jonah Hill has gone through.
