Christian Bale – actor
The English actor Christian Bale has proven himself as an amazingly hard worker during his career in Hollywood. One of the most shocking transformations he went through was between his movie roles for The Machinist (2004) and batman Begins (2005). In the former, Bale plays a man who suffers from severe mental issues, such as a complete lack of sleep. He completely starved himself which led Bale to lose no less than 28 kilos for this role.
