Wiseguy is an American crime drama series that aired on CBS from September 16, 1987, to December 8, 1990, for a total of 75 episodes over 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.
Wiseguy originally starred Ken Wahl as Vinnie Terranova, a Brooklyn native and deep cover operative for the FBI under the supervision of senior agent Frank McPike, played by Jonathan Banks. The primary cast was rounded out by Jim Byrnes, who played an information operative known as Lifeguard (real name Daniel Burroughs) who assisted Vinnie in the field. This cast remained together for three full seasons, after which Wahl left the series. The writers conceived a new lead character Michael Santana, and brought on Steven Bauer to fill the role.
The show placed No. 74 on Entertainment Weekly's "New TV Classics" list.
