For those of you, like me, who didn't attend SDCC this year but what to know what the heck is going on with Venture Bros., here's a rundown of all the goings ons.
The biggest news is that the previously announced long-form episode will be a one-hour special that airs between seasons five and six. Season five will end likely in March or April (depending on when it starts) but no news on how soon season six will begin after that.
Geeks of Doom has also reported on (among other things) some of the special guest voices for season five:
Several guest stars were announced for the upcoming season. J.K. Simmons will guest star in the Halloween special. Other guest voices for the season include Aziz Ansari, John Hodgman, Tim Meadows, Gillian Jacobs, and Paget Brewster.
Finally some more into about the Halloween special: it will actually take place after the season five premiere, so there will be a lot of confusing moments in it. This misordered timeline doesn't seem to be entirely intentional on Jackson and Doc's part, but they also seem to be pretty okay with it at this point. Jackson described it as a "happy accident" in at least one interview.
And, as always, keep checking back for any new info, interviews and that sort of thing.
