The Oscar winning actor is no stranger to changing his body drastically for a role. 

McConaughey is starring in the new film Gold, where he plays an businessman who travels to the Indonesian jungle in search of some, eh, gold. We see what they did there. 

He had previously lost over 3 stone for his work in Dallas Buyers Club and that won him an Oscar. A long way away from the likes of Fool's Gold and whatnot. Where he spent an entire production not wearing a shirt - to box office success, it has to be said. 

 

 

 Stephen Gaghan, who directed George Clooney to an Oscar in Syrinana is calling the shots.
