Cannonball is a British/Canadian adventure drama series starring Paul Birch and William Campbell, and aired on CBC Television in Canada, ABC Weekend TV in the United Kingdom, and in syndication in the United States. Produced by Normandie Productions and ITC Entertainment, the series' interiors were filmed at Canadian Film Industries Limited, a studio in Canada. Exteriors were shot in and around Toronto.The series is one of the few ITC productions to air on ABC Weekend TV in the UK. Because Associated TeleVision (ATV) owners of ITC, also ran the London weekend and Midlands weekdays ITV companies, they tended to hold the rights for ITC series in order to show each one in the Midlands (where ABC was the weekend operator) during the week. The series aired from October 6, 1958 to July 13, 1959, for 39 episodes in black-and-white.
