Kate Winslet

My job as the actress playing Hanna Schmitz, as the actress playing any part, is to understand the character, and to ultimately love the character. And I did love Hanna, absolutely, because I understood her as profoundly as I did at the end of the day.

A lot of people give actors credit when they gain weight for a role in a drama when they win an Oscar, but when you're doing a sitcom, people don't give you a lot of credit, because you've got to keep your weight on for five or six years if it's successful.

I haven't modelled since I was 12 - that was a one-time thing, and I did it as a kid to make a little money to save up for university. Acting is my first love as well as writing and eventually producing and directing.
