After doing 'Doctor Who,' I'm open-minded to doing more acting. Part of the reason you do a show like this is because it creates other opportunities you haven't had before.
Eclecticism is the word. Like a jazz musician who creates his own style out of the styles around him, I play by ear.
I have days where I feel like crap and I look at my body and I'm like, 'I haven't been able to work out as much. I can see my butt drooping a little bit.' And I'm just like, 'Oh well.'
