Bad Boys for Life (2020)
1 revealing 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: Will Smith dismisses the new task force "AMMO" as "a high school musical boyband with guns." AMMO member Kelly is played by Vanessa Hudgens, who starred in the High School Musical franchise.
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. Smith is just repeating back the word, not clarifying anything.

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