Named after the emergency telephone number for the United Kingdom, Dial 999 stars Robert Beatty as Canadian Mountie Mike Maguire, and follows his work fighting crime alongside London's police.
Beatty was essentially reprising his role in the 1946 film Appointment with Crime, in which he played Detective Inspector Rogers, a Canadian police officer attached to Scotland Yard.
The show contrasted Beatty's muscular brand of policing with that of his British colleagues, but failed to sell to North American markets.
Notable actors who appeared include Michael Balfour, Adrienne Corri, Vera Day, William Hartnell (who had appeared in Appointment with Crime), Arthur Lowe, Patrick Magee, Sidney Tafler, Patrick Troughton and Sam Kydd Dial 999 was filmed at Elstree Studios, and on location in London.
