Wiseguy is an American crime drama series that aired on CBS from September 16, 1987 to December 8, 1990 for a total of four seasons. The series was produced by Stephen J. Cannell and was filmed in Vancouver, British Columbia to avoid the higher studio costs associated with filming in Los Angeles. Ken Wahl played the title role, but left following the third season. Steven Bauer replaced him for the abbreviated fourth season. The series also starred Jonathan Banks and Jim Byrnes, who were the only two regular cast members to appear in all four seasons. The show placed #74 on Entertainment Weekly's "New TV Classics" list.
