Our "Dark Knight" Christian Bale is absolutely unrecognizable as he has undergone some dramatic physical transformation and is bulking up to play former US Vice President Dick Cheney in his upcoming biopic. He has not only gained weight but also bleached his eyebrows to get the perfect look, shocking his fans.

In an interview to

Variety at the ongoing Toronto International Film festival, Bale 43 opened up about his next transformation as the lead of the upcoming Dick Cheney biopic. The actor said in order to develop the proper body type and gain weight, "I've just been eating a lot of pies." The actor was seen giving his wife Sibi a tender kiss outside the Princess of Wales Theatre at the Toronto International Film Festival premiere of his movie "Hostiles". He was dressed in a 6ft figure in a black three-piece suit, while Sibi coordinated with him in a long-sleeved lace cocktail dress and pumps.

Adam McKay is set to direct the biopic. Also starring in the highly-anticipated flick is his "American Hustle" co-star Amy Adams, who will play his wife Lynne Cheney, while Steve Carell will handle the role of Secretary of Defense Donald Rumsfeld.

Between 2001 and 2009, Cheney assisted as George W's VP. Bush's and was a key player in US foreign policy during that time, particularly with regards to the wars in Afghanistan and Iraq.

In terms of appearance Bale was not an obvious casting choice for Cheney nor was Steve Carell as Secretary of Defense Donald Rumsfeld.

It's not the first time Bale has gone through physical transformations for his roles and stunned his fans. Host 4-and-a-half stone for his 2004 film "The Machinist". He was compelled to drop the weight again in 2010 when he starred alongside Mark Wahlberg in "The Fighter" where he played a former drug addict Dicky Ecklund.
