Spent this evening browsing blogs I hadn't read before (and now am subscribed to far too many, but I will thin out the crop after I watch then for a while), and in doing so found a couple of quotes I love. I'll be using these in my signatures.

One script. One feature. One pilot. One credit. No one in or out of this Guild is more than 120 pages away from the A-list. - Josh Friedman

Cinema and storytelling is there to smash the jail that we've put ourselves in.
- Anthony Minghella

Ones I have already been rotating for my signatures include:

Screenwriting and filmmaking is the most money you can make writing poetry - Gordy Hoffman

Don't tell me the moon is shining; show me the glint of light on broken glass... - Anton Chekhov
