Screenwriting : Dream Director by Maurice Vaughan

Alfred Hitchcock. (You said "dream.")

Maurice, I watched "Cadillac Records" on TV and loved it!

And I'd love to see its director, Darnell Martin, helm "Jingle Belles..." which, by the way, was set in her birth city, New York City.

Nice choices. It's Steven Spielberg for me.

Chris Nolan or Del Toro or Bong Joon-Ho.

Eric - I've been on set with Hitch and watched him work - I noticed that he was a bear to work with.

Julie Traymor? Say what you want, but she puts on screen what no one else does.

Spielberg or Zemeckis would be great.

Spike Lee and Quentin Tarantino

I don't really think that way when I write but my first script was written with Spike Lee in mind. The only other project I ever seriously thought about the director was a script I haven't taken the time to write that would only work if directed by someone who can get away with a lot of nonsense like James Gunn.

Steven Soderbergh or Scott Frank.

I think I'd go along with Greg McLean but only on my latest one, being somewhat inspired by one of his own films...my next script is already booked for a specific director (sorta speak) as we did some work together before and I've pledged him exclusive preview.

Great answers, everyone.
