The film starred Bowser, Jimmi Simpson, Kevin Corrigan, Mark Boone Junior, Dee Wallace, Craig Anton, Ruby Wendell, F. Jason Whitaker and Chris Hardwick.

They created The Underground which starred Bowser as a man who lived in the basement of the network and hacked into their broadcast feed to air sketches and interstitials that featured him and his puppet co-horts.
