KCRW Martini Shot with Rob Long
KCRW The Treatment with Elvis Mitchell
Filmspotting with Adam Kempenaar and Matty Robinson
Creative Screenwriting with Jeff Goldsmith
On The Page with Pilar Alessandra
The Dialogue was great but it hasn't been updated in 2 years.

Filmspotting, Creative Screenwriting and On The Page are the three I'm listening to as well.

More I can't manage ;) but I'm intrigued by the KCRW
