Though born and mostly employed in England, his early life in
Canada gave him such a perfect ear for the North American accent that
many of his best remembered roles (such as the voice of Jeff Tracey in
the
Thunderbirds (1965) TV series) were Americans. He was for many years a
member of ITC's stable of character actors, and in one episode of
The Saint (1962)--"The Bunco Artists"--he plays a con artist who starts out with
an American accent and later reverts to British.
