Martyn Huntley's Doctor Who career began as a simple walk on part as 'First Human' in the Sensoriates story. He had very little more to say, but a more significant role as a Roboman, the human slave of the Daleks in Dalek Invasion of Earth. Two years later, he was Wyatt Earp's brother Warren in The Gunfighters, the only attempt Doctor Who made at a Western adventure.
