Tenniel Evans
From Tardis Wiki, the free Doctor Who reference
Tenniel Evans played Major Daly in the Doctor Who television story Carnival of Monsters.
Evans was an old friend of Jon Pertwee, having appeared opposite him in the long-running BBC radio comedy The Navy Lark. He suggested that Pertwee audition for the part of the Third Doctor after hearing of Patrick Troughton's departure from the role; Evans was unaware that the Doctor Who production office was already considering Pertwee for the role[1].
When Patrick Troughton died, Evans took over his role in the ITV sitcom The Two of Us.
