Los Angeles, March 9 (IANS) Hollywood actor Paul Bettany has revealed he is having a nightmare with the publicity drive behind his latest movie 'Legion'.

Bettany says he gets embarrassed when he takes his two children with actress wife Jennifer Connellyto school because he sees bare-chested posters of himself from the apocalyptic film all over the place.

'There are these posters up all over the place of me bare-chested. It's kind of peculiar because I take the kids into school and they're like Dad it's you. I'm like 'shut up shut up'. It's not the kind of thing you want everyone seeing on the school run,' Bettany said in a statement.

With the release of 'Legion', Betany, 38, also revealed he's worried about his kids' futures.

'I think about the apocalypse all the time in terms of the environment and in terms of the wars we're waging. I think about it a lot, and it's frightening what life is going to be like in 2055 for my children if we don't cut down on our fossil fuels,' he said.

'I think it's an ongoing fear and fantasy for people, so I don't think it's ever gone away. And maybe that's why we're suddenly seeing so many post-apocalyptic movies,' he added.
