In the film Bruce Jones payed a character called Reg. Here, he is named Vince.
Despite being a main character in the film, this is the last appearance by Hugo Speer as Guy in this series. His appearances here have been limited so possibly reduced with hindsight after the actor was sacked from the show for impropriety.
The first of just two appearances by Emily Bevan as Yvonne. Her role may have been curtailed by the removal of Guy from the show after this episode, the man she is due to marry.
