Mel Gibson has told how he felt sorry for Edge Of Darkness director Martin Campbell.
The Lethal Weapon star - who took time out from acting to direct The Passion Of The Christ and Apocalypto - returns as a lead actor in Edge Of Darkness, the movie version of the 80s BBC TV series, and talked about how working as a director has changed him.
Mel said: "Well I think the main thing you have is empathy for the director - it's like you look at the guy and you go 'poor b*****d' because they run you ragged."
He added: "And of course your job there is to help him achieve what his vision is, so you're there but the workload seems less, and indeed it is, because you're a component in the process of storytelling whereas with the other gig, you've got to be on 24/7."
The 53-year-old actor, who has taken a few minor acting roles recently and is planning to now balance acting with his forthcoming filmmaking projects, also revealed what he looks for in a role.
He said: "What you're after is really kind of some fulfilment in what you do and have other people relate to it, and if it starts to feel stale, you've got to re-examine it, I think.
"And I really like the experience of stepping away from that and getting behind the camera. It's great, that's the best. And I'll do that again soon too, I'll just break it up a little."
