!!The film

* WhatCouldHaveBeen:
** Creator/MichaelWinner originally wanted Creator/MartinSheen for the male lead but Creator/{{Universal}} didn't think he was a capable film actor so Sarandon was cast instead.
** Music/JohnWilliams was originally attached to score the film but pulled out to do a little film called ''Franchise/StarWars'': ''Film/ANewHope''.

!!The TV series

* NamesTheSame: No, our intrepid hero has never sung lead for Material Issue or served as mayor of [[UsefulNotes/{{Detroit}} Royal Oak, Michigan.]]
* PropRecycling: The police uses the same Dodge Intrepids with exactly the same paint scheme as the Metro City police in ''{{Series/Viper}}''. Both TV series were filmed in Vancouver and Canada in general respectively; both series were produced by Paramount (while ''The Sentinel'' aired on UPN from the start, ''Viper'' began on NBC before moving to syndication, often on UPN stations).
