P.R. (TV series)
P.R. was a Canadian television sitcom, which aired on CBC Television in 2000. The show starred Diane Flacks as Alexandra Reed and Ellie Harvie as Jill Hayes, partners in a public relations firm. Fiona Reid also starred as office manager Dierdre Duncan, a mysterious older British woman in the vein of The Avengers’ Emma Peel, who frequently hints at a shady past.
The show was widely characterized in the media as a Canadian adaptation of Absolutely Fabulous, although its humour was much less campy.
The show ended after 13 episodes.
