The All-Night Show was a television series starring Chas Lawther and produced by Jeff Silverman which ran from September 1980 to August 1981 on CFMT-TV in Toronto. The show ran live nightly from the end of other programming until 6 am. The premise was that Lawther's character, Chuck the Security Guard, had, with the help of his never-seen technically minded friend Ryerson Dupont and P.B. Leonard, took over the facilities of CFMT and accidentally broadcast their favorite shows over the air while fooling around with the equipment. The All-Night Show generally showed reruns of classic series such as The Twilight Zone, The Outer Limits, and The Prisoner, and filled the space in between with music videos, old movie shorts, and comedic banter. The show only lasted one year, ending when CFMT cut its budget for the time slot. Jim Carrey was featured in some episodes of The All-Night Show, primarily as a voice actor.
