Pearson continued to create covers for Target, including new covers for reprints of Doctor Who novels - some using artwork originally painted for the BBC Video releases - including An Unearthly Child and The War Games.
On The Space Pirates Sherwin briefly resumed his old role as Dicks was busy writing The War Games.

Sherwin was responsible for the idea of exiling the Doctor to Earth (which happens at the end of The Second Doctor's last story, The War Games), a decision he took in an attempt to improve falling viewing figures, reinvent the programme and bring more reality to Doctor Who by basing it more on The Quatermass Experiment.
He played the Security Chief in the 1969 Patrick Troughton story The War Games, Nefred in the 1980 Tom Baker story Full Circle and Keeper of the Matrix in the 1986 Colin Baker story The Ultimate Foe.
Other sci-fi appearances include two Doctor Who stories, The War Games (1969) and The Face of Evil (1977), and as prison ship officer Raiker in the Blake's 7 episode "Spacefall" (1978).

Previously Martin appeared in the show itself as a Time Lord in the 1969 serial The War Games opposite Second Doctor Patrick Troughton and later guested in the 1993 Doctor Who radio play The Paradise of Death alongside Third Doctor Jon Pertwee and the 2003 Doctor Who audio drama Flip-Flop alongside Seventh Doctor Sylvester McCoy.
Sherwin succeeded Peter Bryant as producer of the programme in 1969, overseeing the production of The War Games and Spearhead from Space.
Dicks has credited Sherwin with the creation of the Time Lords, who were introduced in The War Games, scripted by Dicks and Malcolm Hulke.
