Executive Meddling: The level of influence NBC tried to impose upon the show during its run on the American network is the stuff of legend.
They sent executives up to Edmonton to provide input into the show's development (which the cast and crew often ignored because it was stupid), gave them minimal budgets for each episode, and aired the show at odd hours (11:30 PM??? on a Sunday?). It's a wonder the show survived, and even thrived, despite these setbacks.
When the CBC picked up the show, they demanded a segment of "identifiably Canadian content," despite the fact that the show was already a fully Canadian production. So, they created a sarcastic reply in the form of "The Great White North", with Bob and Doug McKenzie.
In another instance, after the cast spent most of the production budget in "Doorway To Hell" on a several-minute long crane shot, the network cut their budget to almost nothing for another episode, "SCTV Staff Christmas Party". The end result is half an episode mixed with fifteen minutes of John Candy (as washed-up star Johnny LaRue) speaking about his memories of Christmas and lamenting his career on a street corner in the middle of winter. This is also one of Candy's finest acting moments.
A few instances of Executive Meddling in the creation of the NBC Network 90 series worked out OK, such as the idea of "wraparounds," or thematic station-based storylines connecting the various sketches, and the inclusion of musical guests.
Some of the network's contemporaneous ideas weren't so good, though, like a suggestion to move "sex bits" to later in the broadcast, and "drug humor" up front for "youth appeal." This didn't make much sense, though. SCTV was, by and large, a lot more conservative in that regard than the Saturday Night Live crowd. There were relatively few sex references on the show, and practically no "drug humor" whatsoever.
Most of the episodes from the show's first three seasons (which were filmed in Canada) and the sixth season (which aired on U.S. pay station Cinemax) are unavailable on DVD, possibly due to rights or music issues.
Likewise, the television special The Best of SCTV (which aired on ABC, and acted as an epilogue to the series) hasn't been seen since its initial television airing. It can be found through torrents, though.
Stunt Casting: Several musicians also acted in skits, including Natalie Cole, Tony Bennett, Hall & Oates, and The Boomtown Rats. Several actors also appeared, including Sir John Gieguld, Al Jarreau (who starred in a parody of The Jazz Singer) and John Marley (Jack Woltz from The Godfather, playing the exact same character as the one from the film).
The Pete Best: Harold Ramis was a cast member for the first season along with serving as head writer, but decided to focus on writing for the next season, before leaving the show entirely.
Robin Duke and Tony Rosato joined the cast for season three, but were hired by Saturday Night Live and left before SCTV made the move to NBC.
