In the ice bar, Shawn mentions that he has only been to Norway once, with his brother in law, and Gus says that they don't talk about it. This is likely a reference to the cliffhanger at the end of the first Psych movie where they mention going to Oslo, Norway.

After Psych: The Movie (2017), creator Steve Franks indicated he wanted to make five more Psych movies.
Dulé Hill and Jazmyn Simon are married in real life. During filming, Jazmyn was 8.5 months pregnant with their first child together (she has a daughter from a previous relationship). Her pregnant belly was hidden behind car doors, counter tops, etc and when creative filming didn't work CGI was used to "erase" her baby bump. Director/Writer Steve Franks was worried Jazmyn would go into labor during her 3 days of filming and they wouldn't be able to complete her scenes. However that didn't happen and Dulé and Jazmyn welcomed their son, Levi Dulé Hill, on May 10, 2019.
While Psych: The Movie (2017) was a special moment and a tribute to the still-ravenous fandom behind Psych (2006), the initial chances for a sequel movie weren't as auspicious, due to the schedules of the main stars. James Roday Rodriguez is a main cast member on the thriving ABC drama, A Million Little Things (2018), and Dulé Hill joined the cast of USA's Suits (2011) in late-2017. Additionally, Maggie Lawson joined Fox's Lethal Weapon (2016) for what would become its final season. Yet, all the dilatory issues experienced by the sequel project in its early conception were dwarfed by a tragic setback for Timothy Omundson, who is recovering from an April 2017 stroke, which left his mobility limited, and kept him out of the public eye for some time. However, despite the sequel project's seemingly snake-bit status, the cast and crew of Psych managed to find a way make things come together. They even found a clever plot-relevant way to work with Omundson's current condition.
