For me, I just try to make sure I eat enough and drink enough water and that's about it.
I happen to be a huge 'Lord of the Rings' fan. I do an annual marathon of the extended editions.
I have to tell everyone that when I finish a film and it goes out and is released, I never look at my films again. I don't like looking back. I don't even like talking about 'em! So I'm really digging back in my memory because I don't like to sit and look at my films again.
