Deliberate mistake: To meet Manny, Mike walks through his store. The last obstacle is a PVC curtain. The camera has to go through the curtain, moving it and thus revealing its presence. However, it is definitely a deliberate artistic choice. (00:32:50)

Bad Boys for Life (2020)
1 deliberate mistake - chronological order
Directed by: Adil El Arbi, Bilall Fallah
Starring: Will Smith, Martin Lawrence, Joe Pantoliano, Vanessa Hudgens, Alexander Ludwig, Jennifer Badger
Continuity mistake: When Marcus is holding his baby grandson, the position of the woman next to him is inconsistent in every single shot. (00:03:55)
Detective Marcus Burnett: We're not just black, we're cops too! We'll pull ourselves over later.
Trivia: During Meghan Burnett's wedding, the guy on the mic giving a quick speech is none other than Bad Boys 1 and 2 director Michael Bay.
Question: In his reaction to Rafe calling him "Grandpa," Will Smith says, "Just cause I f*ck your mother don't make me your Grandpa, right?" That's... not how it works. Wouldn't the joke be "Just cause your mom calls me Daddy," etc.? (00:46:30)





Answer: It's not about the relationship. "Grandpa" is used as slang or an insult to mean someone is old.

But the point is Will Smith's response - "f*cking your mother" wouldn't ever make them someone's grandpa.
