Behind the scenes

 * Doctor Who: The TV Movie was filmed in Vancouver, B.C. in 1995-96, the first time a Doctor Who production had been mounted in North America.
 * Canada was the first country in North America (and one of the first outside the UK) to see broadcasts of Doctor Who when the Canadian Broadcasting Corporation debuted the first season in 1964 (it was cancelled a year later, however). In 2005 Canada repeated history by once again becoming the first North American country (and one of if not the first non-UK countries) to see the revival series, again on the CBC.
