Edward Kelsey

Edward Kelsey (born 1930) played a Slave Buyer in The Romans, Resno in The Power of the Daleks and Edu in The Creature from the Pit.

According to the DVD commentary for "The Slave Traders", the reason for Kelsey's repeated return to Doctor Who was because Christopher Barry — the director common to all three of Kelsey's stories — liked to draw from a stable of reliable actors for his supporting casts. The commentary further claims that Kelsey is notable as the first non-regular actor to appear with two different incarnations of the Doctor.
