The love scenes that worked, regardless of the director, were the ones where the actors weren't fearful. When somebody was fearful, you could see it right away. It takes you out of the story, and that's to be avoided at all costs.
I think I could walk into any music shop anywhere and with a guitar off the rack, a couple of basic pedals and an amp I could sound just like me. There's no devices, customized or otherwise, that give me my sound.
I really like to experiment. That's the only way I can work. It's instinctive.
