When Murtaugh first talks to Ethan, he says the same thing his movie counterpart said to Albert in Lethal Weapon (1987).
Portions of this episode were filmed at the original Hollywood Park Casino building, inside what was once the structure which contained the southernmost grandstand of the racetrack, which itself closed in 2013. In October 2016, an all-new Hollywood Park Casino opened elsewhere on the property. The building featured here was demolished in late 2016 and early 2017 to make way for construction of SoFi Stadium at Hollywood Park, home of the Los Angeles Rams and Los Angeles Chargers football teams. The stadium opened in time for the 2020 NFL season.
