If anyone is wondering how Cushing fits in to the Doctor Whoniverse, he starred in two sixties era films, Doctor Who and the Daleks and Daleks' Invasion Earth 2150 A.D. They were made to capitalize on how insanely popular the Daleks were after their debut in the second story of the TV series. They aren't 'real' in the sense of being part of the canon. The characters have different backgrounds and such.
