His only full acting appearance was as Professor Grisenko in the Doctor Who Series 7 episode, Cold War. Three years earlier, he had also played another professor in an Ice Warrior story, when he voiced Professor Boston Schooner in the New Eighth Doctor Adventure, Deimos.
Previously, in 2009, he played Lord Azlok for the BBC-produced animated Doctor Who serial, Dreamland, co-starring David Tennant, but perhaps his most celebrated voice only role is that of an Unbound Doctor.
Outside of Doctor Who, Warner has been involved in many legendary film and TV productions, including Tron, James Cameron's Titanic, The Omen, Time Bandits, and Z-Cars, as well as various roles in the Star Trek and Batman franchises.
In 2005, Warner also appeared in The League of Gentlemen's Apocalyse, written by and starring Doctor Who writer/actor Mark Gatiss, who also wrote Cold War.
