Trivia: K Callan, who plays Christopher Plummer's mother in this film, is actually six years younger than Plummer in real life.
Trivia: At the end, Benoit Blanc says he noticed the blood on Marta's shoe the first time she stepped in front of him.

Trivia: Michael Shannon has played Jaeden Martell's father twice on screen, in this movie and Midnight Special.
Trivia: Jacob Thrombey, the far-right troll, was based in part on the backlash and targeting that Rian Johnson experienced after The Last Jedi was received unfavourably by some people.
