This episode contains three references to Noah Wyle's long-term role on ER (1994). While his character Harry Wilson is at a hospital, someone pages a "Dr. Ross" over the intercom, possibly a reference to George Clooney's character on ER, Dr. Doug Ross. At 29:50, when he decides to pretend to be a doctor, the background music sounds similar to the original ER theme. Later, Sophie asks Harry how he managed all the medical jargon he used to pass as a doctor in that scene, and he answers, "TV!"
The episode shows some influence from the movie Key Largo. In the movie, criminals take over a hotel while a WWII vet is on the premises. Here Eliot (also a vet) and Parker end up stuck at a hotel taken over by corrupt police. The movie's protagonist played by Humphrey Bogart is named McCloud. The episode claims the name for the hotel's owner.
The cops are named alphabetically: Abel, Boggs, Collins, Daniels, Ertz, Finch, and Griffin.
The last scene has Parker commenting that Law & Order (Maria) did well. Guest star Andrea Navado played Det Cordova on the original Law and Order in the early 2000s
Eliot (Christian Kane) defends against the bad guy who is wielding a pool cue. Christian Kane guest stars on Supernatural (2005-2020) in the episode Last Call (Season 15, Episode 7) as the bad guy and is killed with a pool cue.
