Chuck addressed the audience directly, and introduced the night's programming from a TV studio control panel—actually placing the video tapes in the playback machine to be played on air.
Occasionally, Chuck would venture beyond his base in the CFMT TV control room and explore the empty station at night while doing his rounds; memorably, he once broke into real-life station president Dan Iannuzzi's office and made himself at home in Iannuzzi's absence.
[2] The other ever-present regular on the show was Chuck's often-heard but never-seen friend Ryerson Dupont (Errol Bruce), the Scottish-accented camera operator.
(Behind the scenes, Bruce and Lennick really did operate the camera and run the audio system, and were also the show's co-directors.)
When LaMarche left the show, a young up-and-coming comic named Jim Carrey was recruited to take his place as a voice actor.
There were periodic contests, with viewers being invited to correctly guess the origin of old movie clips, or to identify actors in the TV series being shown.
One memorable contest featured producer Jeff Silverman (in character as a pirate) giving clues to the location of a buried treasure.
Notable musicians who appeared on The All Night Show included James Cotton, Richie Havens, David Wilcox, Domenic Troiano, Bruce Cockburn, Burton Cummings, Mary Margaret O'Hara and King Biscuit Boy.
