- Actor Allusion:
- While the detectives are investigating a college murder, Frost asks, "Where did you go to college, Korsak?" Korsak's answer: "Didn't, watched Animal House a few times." Korsak is played by Bruce McGill, who played D-Day in that movie.
- Maura references an extensive background working with federal agencies. Her actress Sasha Alexander previously portrayed a Secret Service Agent that then became an NCIS Agent.
- California Doubling: The show is so obviously filmed in LA it borders on embarrassing. Frequent shots of palm trees, which are literally unable to survive in Boston's climate, buildings almost all being built in an architectural style that was developed decades after most of the city was built, streets in an orderly layout that simply does not exist in a city that pre-dates urban planning, and the near complete absence of Boston accents in the cast make for a setting that amounts to an Informed Location.
- The Cast Showoff:
- One episode sees Maura demonstrating fluency in Serbian. Sasha Alexander has a Serbian mother.
- At the end of "Knockout", Bruce McGill gets to show off his skill as a singer and guitarist.
- The Character Died with Him: Detective Barry Frost. He died in a car accident after actor Lee Thompson Young committed suicide.
- Filming Location Cameo: The season 6 episode "Fake It 'Til You Make It", where Rizzoli and Isles fly off to L.A. after discovering that an earlier killing there might be linked to their current case. They did at least one scene at the beach.
- Hide Your Pregnancy: Sasha Alexander was pregnant with her second child during Season One. Sometimes it's well hidden and sometimes not as much. In "I Kissed A Girl", Maura was in baggy shirts or scrubs for half the episode and skintight outfits for the other half.
- Missing Episode: Apparently there are two, according to Twitter.
- Name's the Same: Jane's surname, Rizzoli, is the same of a famous Italian publishing house that even has an American branch and which publishes the Rizzoli & Isles books in Italy!
- Typecasting: Two series in a row may not be enough, but Angie Harmon's last show had her as a tomboyish cop who is married to the job (the difference between Women's Murder Club and Rizzoli & Isles is that her character was divorced in WMC and single by choice on this show). This is also her third law show, but on Law & Order, she was an A.D.A., not a cop. Averted for Sasha Alexander, who was on a law show the last time she was on TV, but she goes from a federal agent who can hang with her male counterparts on NCIS to a more feminine ME with an advanced degree here. Donnie Wahlberg, on the other hand, seems to be type-cast into the cop role. Harmon played a tomboyish detective on Baywatch Nights.
