Billy Bob Thornton has a crippling fear of public places and feels as though he is subjected to a "witch hunt" every time he leaves home.

The Bad Santa star suffers from a mild form of agoraphobia, which leaves him feeling vulnerable when he steps outside, and his condition has become increasingly worse over the years.

He tells CNN host Piers Morgan, "I wasn't always that way. I've been driven inside in the last few years a lot more. I'm more afraid of people now. Not afraid of them physically - it's like this social network, it's kind of a creepy thing to me. I know that sounds like I get signals through my head from Mars, but I'm just observing people's behavior these days."

"There's a real lack of privacy now. We're living in a more cynical society. That's one of the reasons I like to stay at home. It's almost like a witch hunt out there in some ways. It kind of creeps me out, so I stay in the house."

However, the actor admits there is one special event he could be tempted to leave home for - the wedding of his ex-wife Angelina Jolie and Brad Pitt.

He adds, "If I were invited, I would go... They're friends and they're great people. But if I didn't go it certainly wouldn't be because of being uncomfortable (seeing Jolie marry), it would be because I don't go anywhere. You're lucky to drag me to a funeral, much less a wedding! Any place I don't go it's simply because I just don't feel like getting out of the house."
