On a simple level, you need directors who are good at action and can choreograph an action scene, but you need them to also have that sense of fun and that sense of movement and that ability to get the actors to really respond to the material in the way that you want them to. It's a very big thing.
'Warm in December, cold in June, you say?'
I don't suppose the water's changed at all.
You and I know enough to know it's warm
Compared with cold, and cold compared with warm.
But all the fun's in how you say a thing.
