Robert Carlyle has hit out at reality TV shows, saying they are killing off drama.

The Trainspotting and Full Monty star told Radio Times that Big Brother should have been a one-off.

"Reality shows make me sick," he said. "I remember many years ago thinking the first Big Brother was amazing; but it should never have happened more than once.

"Those people in that first show had no idea what was going on outside, didn't adjust their behaviour accordingly. Now they're all doing that so you don't get any sense of real people at all. It's the death of drama."

Robert said becoming a father had changed his approach to roles.

"There are certain parts nowadays that I would turn against. If I had to play someone who was harming children, I couldn't do that. In the past I would have done anything," he said.

The Scottish star now lives in Canada and has no intention of returning any time soon.

"At this point in my life I'm happy here in Vancouver, although I miss a lot of stuff culturally and I feel for the people back home just now because I know that the country's been through some pretty tough times," he told the magazine.
