I THINK IF YOU'RE GOING TO BE CONVENTIONALLY ROMANTIC YOU'VE GOT TO GO ALL THE WAY: A BEAUTIFUL DINNER SOMEWHERE LOVELY, WITH BOAT-LOADS OF FLOWERS, CHOCOLATES AND CHAMPAGNE.

I'm sure favorite moments in movies are things that just happen accidentally when the camera is there. You have to do all the homework to get yourself into the period, the costumes, the style, the voice, the hairdo or whatever it is, but once you've done all that work, you have to kind of let it go and just be there.

The thing that keeps you grounded is doing the thing you love.
