Tamsin (In 1997, talking about her upcoming marriage to Richard Leaf): It suddenly hit me one day: after we're married I'll be called Mrs T Leaf!
(on her BAFTA and Royal Television Society Award nominations for "Green Wing")
Tamsin: I feel very privileged in getting my work recognised but I confess that I also felt a bit odd in getting it for Green Wing, given that it is such an ensemble piece. Isn't it a bit peculiar that you could say, 'Right, which is the best colour in the rainbow? Which one shall we give an award to?'. And you pick one colour out and then it's not a rainbow any more. I suppose, in the final analysis, it is about people relating to a character rather that giving marks for a performance.
(on balancing career and family)
Tamsin: I was very blessed. When I first had children I had no huge career to surrender, no great dilemma about work versus family. If someone had said back then: 'One day you will be in three TV shows and radio and breast-feeding a baby,' I'd have said 'no way'. A career on a slow burn has been perfect for me.
(on finding God at age 30)
Tamsin: When I came to faith, I thought I would have to stop being an actor, because it's all about artifice and manipulation. But we're living in a world where God doesn't really have an influence, unless it's fundamentalists, so I'll always be an outsider because of my faith. And when you think about it, faith and acting are all about stories, so the two are not mutually exclusive. I decided to try to use what I'd been given in a creative way.
(on why she would never make it in Hollywood)
Tamsin: I'm far too puffin-faced for that, too weird-looking. No, I think I'll probably stick to telly, if telly'll have me, though I wouldn't mind doing radio plays as well. I always did enjoy radio.
(on finding love)
Tamsin: I do think there's someone out there who is perfect for you but you have to have your eyes open and your heart ready to recognise it when it comes and you can't be obsessive about looking for it. It's a bit like catching a bus you can't make one come along but you can be ready to jump on it when it does it.
(on her work-life balance)
Tamsin: It can get tricky, yes, when things all happen at the same time. I'm doing a full time job now, which means I see them less than I want to. But I suppose that's the cost of working. I have a lot of support and a lot of encouragement, and very forgiving children.
Tamsin: We all engage in dysfunctional relationships, of abusive interdependence and mutual shafting.
Tamsin: We should all live with an eager sense of hope and utter lack of shame.
