Serials

Barry Letts took over as producer from Derrick Sherwin after Spearhead from Space. From this season onwards the programme was produced in colour. To accommodate the new production methods the number of episodes in a season was cut: season 6 has 44 episodes; season 7 has 25 episodes. The seasons would continue to have between 20 and 26 episodes until season 22. Following the opening four parter, the remaining episodes were divided into three serials each of seven episodes. This, along with setting the entire season exclusively on Earth, had been the choice of Peter Bryant and Derrick Sherwin, which Letts and script editor Terrance Dicks were unhappy with.

Spearhead from Space was intended to be produced identically to previous serials, with a mixture of location material shot on 16mm film, and studio based material on videotape. Owing to industrial action by studio technicians at the BBC, the planned studio recording sessions were cancelled, with instead all four episodes being shot on location on 16mm film.

Inferno is the nickname given to a project to penetrate the Earth's crust. The project, however, has its own problems and the Doctor is sent to an alternate universe.

Broadcast

The entire season was broadcast from 3 January to 20 June 1970. Peter Bryant and Derrick Sherwin had originally envisaged replacing Doctor Who with a Quatermass-style serial, with Nigel Kneale involved, but this fell through when Kneale refused to write for the show. The plan did, however, have an effect on the programme, seeing the Doctor exiled to a near-future earth as UNIT's scientific advisor.
