Sadly, Namu died soon after the film was made; incredibly, from drowning.
Stock music by Robert Van Eps and Dominic Frontiere was integrated into Samuel Matlovsky's original score for "Namu". Van Eps' music was composed for "The Outer Limits" TV segment entitled "Tourist Attraction", which was directed by Namu's László Benedek. The ominous-sounding cues were used for the amphibious fish-monsters, the Ichthyosaurs.
