- Directed by Cast Member:
- Georg Stanford Brown directed several episodes of the series, near the end of the third season and into the fourth season.
- Gerald S. O'Loughlin directed the episode "A Time to Mourn". He also directed an episode of another Spelling-Goldberg series, Family, but unlike Brown, decided that directing wasn't for him and continued his acting career.
- Fake American: Canadian actor Michael Ontkean as American Willie Gillis.
- Keep Circulating the Tapes: Only the first two seasons are available on DVD. Considering the poor sales of the first two sets, it's highly unlikely the remaining two seasons will be released.
- Name's the Same: The young girl who is struck and killed when she's chased into the path of a car in "Someone Who Cares" is named Karen Austin, just like the actress who played Lana on Night Court.
- Huggy Bear is the name of Terry's informant in "Prayers Unanswered, Prayers Unheard", same as the informant on Starsky & Hutch. William Blinn, who created Starsky & Hutch, had a hand in creating The Rookies.
- Playing Against Type: Jim Nabors in the episode "Down Home Boy" plays a man who's out to kill a country singer he blames for his sister's death.
- Real-Life Relative:
- Georg Stanford Brown's then-wife, Tyne Daly, appeared in each season of the series, in the episodes "A Farewell Tree From Marly", "Time Lock", "Cliffy" and "From Out of the Darkness".
- Dan Spelling, Aaron Spelling's brother, guest-starred in a pair of episodes.
- Similarly Named Works: The episode "The Shield" does not feature Michael Chiklis, Walton Goggins, or any other cast member from that series.
- Acting for Two: In the episode "The Shield", Jonathan Goldsmith, billed here as Jonathan Goldsmith Lippe, played both an accused cop killer and his lookalike, who happened to be the real killer.
