The script [of Regression] wasn't the draw for me. It was largely Alejandro [Amenabar] and his way of talking. To hear him talking about the script was way more interesting than the script. He wrote it, and so, English is his second language. It's an interesting thing. I've had that before. I was directed by Alfonso CuarĂ³n before, too. It's always interesting when you're being directed by somebody like that. So much of directing is about communication, and finding the right words, and what it means, and how to convey certain emotions and ideas.
