Bob Robertson (comedian)

Double Exposure was a Canadian radio and television comedy series which satirized contemporary Canadian politics. The show starred Linda Cullen and Bob Robertson, and focused primarily on the stars' voice impersonations of Canadian political and cultural figures. In addition CBC staff announcer Bob Sharples provided the introductions and conclusions to Double Exposure shows and provided narraration for many Double Exposure skits.

It played on CBC Radio (now known as CBC Radio One) at 11:33 a.m. on Saturday mornings, and on CBC Stereo (now known as CBC Radio 2) Saturday evenings at 6:32 p.m. (one half-hour later in Newfoundland). Unlike many previous CBC radio comedies, such as The Royal Canadian Air Farce or Frantic Times, the show would be recorded wholly in a studio without a live audience. The duo made the jump to television with an initial satirical special in 1994, and became a television series in 1997.

The radio version of the show ran from 1986 to 1997 on CBC Radio. Prior to the launch of their own show, Robertson and Cullen were known as regular contributors of comedic sketches to Jack Farr's The Radio Show.

It satirized contemporary Canadian politicians such as Brian Mulroney, Joe Clark, Preston Manning, Barbara McDougall, Bill Vander Zalm and others, as well as international figures such as Margaret Thatcher. Robertson specialized in such impersonations as Bill Clinton, Ross Perot, John Major, and Queen Elizabeth, and Cullen could do imitations of Sandie Rinaldo, Princess Diana, Julia Child and Sister Wendy, among others.
