The concept of the Daleks and the Cybermen both appearing on-screen was first proposed in 1967, but was vetoed by Terry Nation, the creator of the Daleks. The episode is the first conflict between the two species in "Doctor Who"s -year history, and features Billie Piper's last appearance in the lead companion role as Rose Tyler; the final regular appearance of Noel Clarke as Rose's ex-boyfriend and previous companion Mickey Smith; and the final regular appearances of Camille Coduri and Shaun Dingwall as Rose's parents, Jackie and Pete Tyler.
