(speaking in 2001)
Dervla: I have spent half my life in the business and I want longevity. I want to produce [she has just acquired the rights to a novel] as well as act. I hope that in the future, I can strike a balance between doing great, interesting TV and unashamedly commercial stuff. And why not? We are here to entertain. This is a job which demands leaps of faith. Why play safe all the time?
