Best known for his roles in Casualty, Soldier Soldier and Reckless, Robson is used to dramas which demand his being the main man rather than dramas such as Trust, in which he is one of several lead characters.

"I honestly never think of myself as a lead", confesses Robson. "I think of myself as an actor in a very good story, and the same applies to Trust. The script was excellent; as soon as I got it I just thought that the visual grammar was wonderful. I thought the words were divine and knew it was something I wanted to do; something I wanted to be a part of, irrespective of what order my name came in the cast list."

The calibre of the acting talent in Trust also impressed Robson, but the atmosphere on set was far more entertaining than your average city law firm. "It was just an absolute ball. We had no problem taking the fun we were having off camera and making sure that it was evident on camera, too. Sarah's so amusing and very easy to work with. Ian, Neil, Chewi and Eva were all vibrant and had incredibly witty energy. At the read-through I knew that it was going to be good. And on a tight filming schedule you need to have fun."

Robson plays Stephen Bradley, a highly successful corporate lawyer who is struggling to accommodate both his work life and his home life. "Stephen is a person who is in pursuit of happiness. He's trying to satisfy three things in his life: his love life, his business life and his personal life. I guess that's what we are all after, but especially in a high-powered industry like corporate law or venture capitalism. You just have to sit down and work out, am I happy? Is my family life happy? Is my work life happy? It's great if you can get all three, but it's virtually impossible.

"Stephen would spend two weekends out of three in the office; four nights out of five he won't be home before ten. He is a man whose life experience helps him understand how this sort of law works. He says that if you take care of the people, then the law will take care of itself - people first, law second. That's the whole philosophy of the show, really."

Trust is not your run-of-the-mill law series. It has a certain fresh quirkiness right from the very first scene, which shows Stephen Bradley waking up in his office after having spent the entire night there. Rather than rushing home to get changed, however, he gets someone in to change, wash and shave him.

"This woman comes in and dresses him - it's a bit quirky. I thought, 'this does not happen'. But there really are services that will come in and bring you clean shirts, then take your dirty clothes away and wash them. I couldn't believe it!"

Robson has been a sex symbol ever since his first big break in TV as hospital porter Jimmy in the BBC's Casualty. So how does he feel about being a pin-up? "It's pure media invention!" he laughs. "I look back at Casualty and realise that it was the best grounding I could ever have had. It gave me political clout and financial clout, and it was great for getting experience of the lens. After that I was put into the category of romantic lead actors. I have a certain look, I have a certain behaviour in front of the camera - that was my key. But as time goes on you start to realise that some of these scripts are very one-dimensional and unrewarding.

"I was looking towards more intelligent drama than something as linear as boy meets girl, girl meets boy, girl and boy fall in love and live happily ever after. I think seventy percent of the scripts I was sent were just love mush. But good love stories are great; Reckless with Francesca Annis - now that was a beauty. What's interesting is that the American stuff that's coming my way at the minute is all baddie parts; nasty, nasty pieces of work."

Green now has his own production company, Coastal Productions, which has made some of his more recent dramas. Having had such a successful career both acting and singing, the next logical step would be for Robson to go behind the camera and try his hand at directing. "I have this great dream that it would be perfect producing some two-hour Brit films, some good drama series, and then acting in some one-offs. That would be fantastic, but if I don't get it, it's not a problem. I can live with failure but not with regret."
