Space Adventure is a series of sci-fi movies. According to Phineas Flynn, it and Stumbleberry Finkbat are the two biggest movie series of all time; it is unclear if he meant literally longest-running or just popular. Like Stumbleberry Finkbat, its special effects were done by Clive Addison. Fans of the series are referred to as "Speckies". The franchise has its own theme song.
