Lew Hunter's Screenwriting 434 has some great chapters about re-writing.

I recommend Paul Chitlik's 'Rewrite'.

Really useful advice, and a good structure for rewriting. I also rate Viki King's rewriting advice in 'How to write a movie in 21 days'.

Thanks for that, Scott!

All good stuff. Looking forward to cracking on with the second draft.
