THR has some heartbreaking news Sunday afternoon as they report that Les Carlson, who played Barry Convex, the evil head of the Spectacular Optical Corp., in David Cronenberg’s hallucinatory sci-fi classic Videodrome, died May 3 at his home in Toronto. He was 81.

Carlson also appeared in three other Cronenberg projects — as an intimidated newspaper editor in The Dead Zone (1983); as a doctor in the Jeff Goldblum starrer The Fly (1986); and as an aging actor in Camera (2000), one of a series of short films produced for the 25th anniversary celebration of the Toronto International Film Festival.

The prolific character actor also was memorable as a pushy Christmas tree salesman in the holiday perennial A Christmas Story (1983).

A native of Mitchell, S.D., who moved to Canada in the 1960s, Carlson was nominated for a supporting actor Genie Award for his performance as the sinister Convex in Videodrome (1983).

A member of a government conspiracy to purge people who are fixated on extreme sex and violence, his character inserts a brainwashing videotape into the “VCR” in the stomach of Max (James Woods), the sleazy head of a station in search of kinky programming.

Carlson also appeared in such other films as Black Christmas (1974) and Deranged: Confessions of a Necrophile (1974).
