The Doctor

Peter Davison makes his final appearance as the Doctor in the The Caves of Androzani. Colin Baker makes his first full appearance as the Doctor in the final serial The Twin Dilemma.

Companions

Janet Fielding (Tegan Jovanka) and Mark Strickson (Vislor Turlough) continue their roles as the Fifth Doctor's companions for their final season, Janet Fielding leaves in Resurrection of the Daleks and Mark Strickson departs in Planet of Fire. New companion Peri Brown played by Nicola Bryant makes her first appearance in Planet of Fire.

The Shape-shifting Android Companion Kamelion, played by Gerald Flood, makes his second and final appearance in Planet of Fire, though the character itself - along with other Fifth Doctor companions who left by this story (Tegan, Nyssa, Adric, and Turlough) - all make illusionary cameos as the Doctor regenerates at the climax of The Caves of Androzani.

Recurring stars

• Anthony Ainley as The Master

Anthony Ainley returns yet again in Planet of Fire as the Master, which was intended to be his final appearance. Ainley, like other departed fifth Doctor companions make illusionary cameos as the Doctor regenerates.

Guest stars

Davros makes his first appearance since Destiny of the Daleks this time played by Terry Molloy.

Serials

Episodes were broadcast twice weekly on Thursday and Friday evenings, with Resurrection of the Daleks broadcast on two consecutive Wednesday nights.

Resurrection of the Daleks was planned as a standard four-parter. However, the BBC's coverage of the 1984 Winter Olympics meant that Doctor Who's normal timeslot was unavailable. Rather than delay broadcasting the story, the decision was taken to produce it as a pair of double length episodes and broadcast it in the unfamiliar Wednesday timeslot.

The Caves of Androzani was the first time since Season 4's The Tenth Planet that the introduction of a new Doctor had taken place before the final serial of the season.
