Actually, it's not so much a podcast as it is a short series of short conversations with Michael Arndt (Little Miss Sunshine) about the writing process, character development, plot turning points, and other interesting tidbits. These videos feature clips from Little Miss Sunshine and are quite insightful, mainly because Arndt speaks candidly about getting the script read, sold and being fired from the project (and subsequently rehired).
I'm not a huge fan of Syd, but I do wish he'd make some more of these.

Unfortunately, I've only been able to find it in iTunes. (There's also an audio version for all you nanos and shuffles out there.)
