Batman Christian Bale is such a fantastic liar in interviews he can no longer be confident he's telling the truth.

The super-private actor refuses to answer questions about his life away from the movies and so he often makes things up to avoid difficult interviews.

He explains, "I'm an actor, I'm not a politician. I always kick myself when I talk too much about family, or personal things."

But he's been doing this for so long he admits the lines between fact and fiction are often a little blurred - especially when it comes to movies he may have been in.

Bale tells Details magazine, "To be honest, it happens a lot. There are so many things which, even knowing that it was in a movie, I still feel like I've been through."

"And then I have to really rack my brain to work out, 'Have I actually been through that in my life?' There are occasions when I've pretended to be in a firefight, and then there are people who have really been in a firefight.

"Clearly it's absolutely ridiculous, and even disrespectful, to suggest that I understand what that is. And it deserves a very hard smack across the face for any actor to ever suggest that they understand. But the power of delusion is incredibly strong." (KL/DT/LR)
