Edmund Warwick

Edmund Warwick played Darrius in the Doctor Who story The Keys of Marinus and, wearing a similar wig, stood in for William Hartnell in the Doctor Who story The Dalek Invasion of Earth after Hartnell hurt himself and could not put in a full appearance. (DWM 280) Though he arguably did not resemble Hartnell very much facially, he also played the Robot Doctor in the Doctor Who story The Chase.

Warwick was most active in the 1950's and 60's, appearing on television shows such as No Hiding Place, Z-Cars, The Adventures of Sir Lancelot (which starred William Russell), The Buccaneers and The Adventures of Robin Hood.
