Trivia: The Sator Square dates back to Pompeii and is a square of 5 Latin words making a palindrome: Sator, Arepo, Tenet, Opera, and Rotas.

Trivia: During one epic car crash near the start, just after the shooter gets taken out by the digger, if you know what to look for you can see Ryan Reynolds in the background, filming a post/advert for social media.
