Seems like every couple years or so I will type in "best movie podcast" in google to see if I am missing something. Seems like I hit a wall with some, especially as they get bigger and get more people talking (for some reason I don't like live podcasts and ones with more than 3 hosts - sometimes 3 is too many). Couple that I tried last week:
Faculty of Horror - by far the one that grabbed me the most. You usually don't have women talking about horror, and here you have two women talking about the genre. I can't remember exactly what they do, but I know they have written books and articles and have done blogs/podcasts. They come at it from interesting angles and talk about what the movies say about us and culture, which is a reason I like the genre to begin with. I tried a newer one first - their discussion about French extreme movies and was hooked, so I started from the beginning. 1st episode was good as they talked Black Christmas and Halloween.
Someone Else's Movie - only listened to a couple, but it was interesting. Basically it's just a guy interviewing random actors and people involved in movies about a random movie of their choice that they weren't involved with - anything from Back to the Future to There Will Be Blood look like they are discussed on this one.
Blank Check - Jury is still out on this one, but it's an interesting premise. They seem to do consecutive podcasts from a common director, and it's basically movies by directors who had success early on, so were given a 'blank check' to do what they wanted later on. M.Night, Spielberg, Cameron, etc..
