What was it like working with Billie Piper again, who returns as Rose Tyler?

“It’s always lovely working with Billie. She’s one of the best actresses around and one of the loveliest human beings, so I was very happy to be in her orbit. It wasn’t strange acting with her again, it’s easy how you slip back into these things. And I suppose it’s not been a massive amount of time. If we’re all brought back in another 20 years it might be a bit different – and we’d be spending even longer in make up! Us being the Doctor and Rose is still within relatively recent memory so it’s not been too difficult to dredge up, although it’s hard to tell objectively whether things are the same or not.”
