My favourite song of Elton's is... it's a tricky one for me. I'm a proper fan and I've probably seen him in concert about a dozen times before I even met him. Mona Lisas and Mad Hatters, which isn't in this film... but whenever I see him, I always tell him that Passengers is my favourite song because it's one of his least auspicious ones.

It's important to hold something back, though, because quite frankly my personal life is pretty dull and I don't want to bore people with it.

It's very likely that graduates, current employees and retirees have some wonderful pieces of Deer Park history in their closets or garages.

But we did see the process develop. I remember going to the Rocket Pictures base and they had something like 40 people there, drawing. They didn't know what the characters looked like yet and I remember on the walls seeing 30 or 40 different versions of Juliet. So, it was then that I realised that someone's got to come in and make some really executive decisions.

People see my impressions as a great skill and I am flattered, but there are things I can't do that everyone else can. I can do funny voices and funny faces but I can't drive.

Honestly, I was just happy to get the work. I was chuffed to bits. I know David Furnish and Elton John a bit and I remember David talking very excitedly about it. This was going back four or five years even, when we were doing Little Britain at the Hammersmith Apollo. I'd lost my voice that night, but still did the show. I remember thinking: "God, they're going to think that's my voice and I'm not going to get in the film!" But it's just been a pleasure to be a part of.

I finally learned to love myself by dressing up as Geri Halliwell.
