Internet gonna have a hard time figuring out the baddie based on the MCU when that ends up applying to the entire cast.
We're going to find out the victim is Spider-Man and Benoit Blanc will have to find out which of his enemies killed the wall-crawler.
i know it's not gonna happen, but my theory is that if Jeremy Renner isn't playing a fictionalized version of himself, this means that in the Benoit Blanc Cinematic Universe, he exists as both an actor and as the face of one of the characters in the film. by that logic, it means that others who've appeared as themselves in a previous installment have license to show up as a completely different character in another installment, meaning that a Poker Face/Benoit Blanc crossover might be possible in the future given that Natasha Lyonne made a cameo as herself in Glass Onion.
DiscussingFilm said Renner wasn’t playing himself, but deleted it and never reposted it, so I’m guessing they possibly had incorrect info or read something wrong.
