Corrected entry: The Cyber leader (black handlebars on the head) is seen being destroyed by the raston robot. It is then seen following the master accross the chess-board. The master then kills it, yet it is later seen giving the order to blow up the TARDIS.
Corrected entry: In episode 4, the Doctor Who producer at this time (John Nathan-Turner) can be seen passing behind the telephone box as the Doctor is consulting the phone book. (He's the one wearing a sheepskin coat). Nathan Turner wandered into the shot while he was "shooing" away "rubberneckers" who had gathered to watch the filming. Nathan-Turner subsequently claimed that his appearance in this Doctor Who story was a deliberate Alfred Hitchcock-style cameo...but was it? It could have been simply Nathan-Turner trying to 'cover up' the mistake.
Correction: It could have simply have been the "rubberneckers" ruining John's cameo.
Correction: There are three cyberleaders in 'The Five Doctors'. Each one controls a team of cybermen. Admittedly it is a little confusing as the same actors play each cyberleader and cyberlieutenant.
