Arthur Spreckley (Grandfather Burns) and Stephen Hall (Young Michael Murray) are credited, but do not appear.
The credits to this series are amongst the most error-ridden in television history, especially as regards the cast. It appears that there may have been last-minute cuts to some episodes (particularly episode 4), made after the credits had already been finalised, resulting in some credited actors not actually appearing in the episode in question. This problem was compouded when the original seven-part series was recompiled to ten one-hour episodes for syndicated distribution, with partly remade credits that introduce new errors even while correcting others. Every effort has been made to rectify these problems.
