You could get the two most fantastic actors in the world, but if the chemistry’s not there, it’s not there. There’s a lot of luck. It was immediately apparent to us, when we started reading - they already knew they wanted Ben for it, but I think they’d seen a few Dr. Watsons, of which I was one - it was just apparent that it lifted the whole thing. Great writing got even better. We both keyed into something that the other was doing.
