Talking about how the onscreen chemistry with co-star Matt Smith was developed, she said:
When I started on Doctor Who Matt said to me “Watch Katharine Hepburn and Spencer Tracy films!” We were talking about our dynamic and trying to figure it out, realising we were a double act . . . It’s trying to find each other’s rhythm... So watching things like Spencer Tracy films really feed into that. Matt always said it’s about physically finding our rhythm... In a way the whole thing is like a dance, and the moment we started dancing together and finding that rhythm is when it worked.The full interview is in SFX 233, in the shops now.
