Big changes came to Doctor Who in its second season, as Carol Anne Ford left the series and a new character, Vicki played by Maureen O'Brien joined. Even bigger changes occurred at the end when Peter Purves joined the crew to replace William Russell and Jacqueline Hill.

But what about their adventures? Well it's the same mix of historical, future and sideways, but with more humour than before.

Which is your favourite from Season 2?
