Jared Leto has shown that he is an actor that is prepared to go to extreme measures of an acting role as the rocker has dropped weight for his The Dallas Buyers Club, in which he plays a HIV-positive transvestite.

But he is not the only actor who is suffering for his art as Matthew McConaghey has also dropped a huge amount of weight to star in the same movie.

So we take a look at some of the actors who have gone above and beyond the call of duty when it comes to preparing for a movie role.

- Christian Bale - The Machinist

Christian Bale has never been afraid to push himself to the limit for a film as he demonstrated with The Machinist back in 2004.

The actor dropped a whopping 62lbs to play a man who is suffering from insomnia - he really did look shocking in the film.

But he went from that movie straight into Batman Begins and had to put 60lbs of bulk back on.

One weight dropping role would be enough for most actors but not Bale as he put his body through the ringer again for Rescue Dawn and The Fighter.

He took on the role of Dieter Dengler in Rescue Dawn where he played a POW while The Fighter saw him play a drug addict former boxer - for the latter he won a est Supporting Actor Oscar.

- Tom Hanks - Cast Away

Tom Hanks lost a whopping 50lbs - which is 25% of his body weight - back in 2000 for his role in Cast Away.

The movie sees him take on the role of Chuck Noland, a FedEx executive who crashes and must survive on a desert island.

As the movie progresses we see Hanks become thinner and thinner in what really was a captivating and emotional performance from the double Oscar winner.

- Steve Zahn - Rescue Dawn

Steve Zahn was another actor who dropped a huge amount of weight for Rescue Dawn as he teamed up with Bale as a fellow POW.

The funnyman had never really gone on a physical transformation for a role before but he lost 40lbs for the role of Duane.

Rescue Dawn is a powerful war movie that sees the two central character break out of the camp that they are being held in and try to survive in the jungles of Laos.

- 50 Cent - Things Fall Apart

50 Cent showed that he was taking his acting work very seriously last year when he lost weight for his role in All Things Fall Apart.

The rapper turned actor went from 15st 4lbs to 11st 2lbs to tell the story of a high school friend.

He played the central character of Deon, a young man with a promising football career ahead of him who is diagnosed with cancer.

- Natalie Portman - Black Swan

And it is not just actors who have been showing commitment to their roles as Natalie Portman lost 20lbs for her turn in Black Swan.

Now let's face it there is not much to Portman to begin with but her tough ballet training schedule saw her get down to a tiny 95lbs.

While the actress was not really comfortably with the way that she looked the hard work was well worth it as she picked up the Best Actress Oscar for what was a stunning performance.
