Stacy Sheridan (Seasons 2–5) Richard Herd as Captain Dennis Sheridan (main cast Seasons 1–2, occasional special guest star Seasons 3–4) James Darren as Police Officer III Jim Corrigan (Seasons 2–5) Hugh Farrington as Detective Lieutenant Pete O'Brien (Seasons 3–5) Production Background The series was created by Rick Husky who had also worked on The Rookies for Aaron Spelling and Leonard Goldberg. The series was originally to be a reworking of that former cop show, this time called The Protectors. After the pilot, it was decided to focus the series on William Shatner's character and retitle it T. J. Hooker. The series initially set out to give a more "hands on", procedure-based view of police work than some of the more stylized cop shows of the 1970s and 1980s, evident in the very early episodes. Setting The LCPD Academy scenes were filmed at the Los Angeles Police Department Academy in Elysian Park. Though the series itself was produced in Burbank and filmed in the Los Angeles area, the setting was not disclosed throughout the show's entire run. Hooker and Romano's radio call sign for their "black and white" was "4-Adam-30", and radio calls were very similar to those of Los Angeles Police Department, using three bursts of a 900 Hz tone, using LAPD-type radio codes, and the officers acknowledging with roger. Vehicles Vehicles used In the first, second and up to the fourth episode of the third season, Hooker drove a '77-'78 Dodge Monaco police package but afterwards he started driving a '79-'81 Dodge St-Regis usually powered by the much more anemic 318 or 360 Cid V8 as opposed to the 440 Cid V8 Monaco! By the Fourth season,when Hooker and his team needed an unmarked cruiser, they usually rolled around in a '82-'83 light blue Dodge Diplomat or a '77-'78 burgundy red Dodge Monaco. Hooker's personal car for the duration of the series was a '74 blue Ford Torino sedan. Romano's car was a gold Datsun 280z and Corrigan's ride was a silver and red Jeep CJ-5. Cancellation and revival T. J. Hooker was canceled by ABC in the summer of 1985 (the final episode was a proposed reworking of the series set in Chicago) but the series survived when CBS picked up the show and produced new episodes (still produced in Los Angeles) and one two-hour TV movie titled "Blood Sport". The new episodes were shown later at night
