'Most of the stars went onto SNL'? No they didn't
Somebody said in the review of this series that "Most of the stars went onto SNL after SCTV" which is a very inaccurate statement.
Only Martin Short had any real success on SNL after leaving SCTV. Tony Rosato and Robin Duke went and spent a season on SNL after basically filling in for Catherine O'Hara and John Candy on SCTV but I seriously doubt many people even remember them on either show.
Dave Thomas, Rick Moranis and John Candy all GUEST-HOSTED SNL at various points in their careers but never appeared in any of the casts. In fact several of the cast members did audition for SNL during the late 70s between the CBC series and the Network 90 series and were rejected by Lorne Michaels.
