 The pilot episode was recorded about 12 months before the series  went into production and was never broadcast. A lot of changes were  made from then. For a start, Davina doesnt appear in the original  pilot episode and was added by the writers later, and the puppets  for Trevor and JP look very different. The plot of the episode is  that Hamish hangs himself and is later bought back to life by  Trevor, who does it by electrocuting him with 50,000 volts. This  plot was later used in the series two episode "Reincarnation".
