Jackson Publick posted a new blog entry on Publick Nuisance today. Entitled “Tonight’s the Night,” he modestly encourages people to watch the season premiere of the Venture Bros. on Adult Swim. With the post, he gives us new information on a special guest voice this season, actor Nathan Fillion. Nathan Fillion is popularly known for his lead role on Joss Whedon’s TV series, Firefly as Captain Malcolm Reynolds. After a Firefly mention in Pinstripes vs. Poltergeists and popular trends by fans on Twitter, Nathan Fillion is set to guest voice later this season.
