Trivia: There is a message left at the end of the credits of the film reading "The staff at the Hotel Artemis hope you enjoyed your stay and that you'll return soon." (01:33:20)
Trivia: Besides a passing reference to 'the wall' to Mexico, there's a more subtle reference to a certain US President in the brand of the generator activated 20 minutes in and at the end of the movie; it's "ковфефе", which is a possible transliteration in Cyrillic of the infamous Trumpian typo "covfefe."
