The series depicts events from September 2004, in which William Shatner played a hoax on the small town of Riverside, Iowa, by claiming to film a science fiction movie there.
In front of and behind the cameras, Shatner and his purported entourage performed a parody of Hollywood and celebrity culture.
Shatner played the part of the eccentric star and improvisational actors were hired as members of his entourage.
Producers chose Riverside because it is the self-proclaimed future birthplace of Shatner's most enduring character, Captain James T. Kirk.
Invasion Iowa was created by Rhett Reese and Paul Wernick, who also created Spike TV's earlier "reality parody" series, The Joe Schmo Show, and its sequel, Joe Schmo 2.
