Doc Hammer attended Dragoncon back in September and there was a Venture Bros. panel of sorts with Hal Lublin (Wide Wale) and Dana Snyder (The Alchemist, who was not in season six). Check out the first part and the second half when you've got a spare hour. Doc goes into some season seven stuff, but they're still in early phases of writing so it's mostly audience questions. Super thanks to MooseyMooz for sending these along.
In slightly more recent convention news we've also got the NYCC panel from a few days ago with Jackson and Doc. I haven't had a chance to watch it yet, but I'm sure they reveal many secrets coming up for season seven! Enjoy!
