Accepting the award, Bale joked: "Thank you to Satan for giving me inspiration on how to play this role."
The film, which was released on Christmas Day, also stars Sam Rockwell as Bush, Amy Adams as Lynne Cheney and Steve Carrell as Donald Rumsfeld. It follows Cheney as he rises up through America's political ranks to become the most powerful Vice President in the country's history.
Taking on the role of George W Bush's former Vice President Dick Cheney, Bale underwent yet another drastic transformation, this time donning a shaved head and bleached eyebrows.
Oh, and a bit of a paunch, too - he reportedly piled on a whopping 3st 4lb for the film.
Yep, if anything deserves an award, it's that.
And if that wasn't enough, Bale also earnt his Golden Globe after saving the life of director Adam McKay.
Cheney famously suffers with cardiovascular disease, having had his first of five heart attacks when he was only 37 - something Bale decided to look into in order to convey the role accurately, researching the symptoms.
When McKay suffered a heart attack of his own, it was apparently a conversation with Bale on set that potentially saved him.
Speaking to Deadline, 50-year-old McKay said: "We finish the movie and I call my trainer. I say, we got to get on it, man. I'm too heavy.
"Our third workout, I get tingly hands and my stomach starts going queasy. I always thought when you get a heart attack, it's pain in the chest or the arm.
"But then I remembered, when we shot one of the heart attack scenes, Christian Bale asked me, 'How do you want me to do it?' And I go, 'What do you mean? It's a heart attack. Your arm hurts, right?'
"He says, 'No, no. One of the more common ways is that you get really queasy and your stomach hurts.' I said, 'Really?' I'd never heard that before.
"And right in that moment [when McKay doubled over] I went, 'Oh shit,' and I ran upstairs and downed a bunch of baby aspirin, and I called my wife who immediately called 911. Got to the hospital really fast, and the doctor said, because you did that, no damage was done, your heart is still really strong.
"That's because I remembered Christian Bale telling me that. The doctor said, you got to quit smoking, that's what's doing this to you. You need to lose weight, but the smoking's making it four times worse.
"I called Christian a week later and said, either you or Dick Cheney just saved my life."
Congratulations, Christian - you've earnt it!
