Character mistake: Gru doesn't recognize Nefario at the record shop, despite meeting him at Villain Con in the Minions movie. And given the fact that he can recognize all of his Minions without even asking them who they are, he should definitely remember seeing Dr. Nefario.
Minions: The Rise of Gru (2022)
1 character mistake
Directed by: Kyle Balda, Jonathan del Val, Brad Ableson
Starring: Steve Carell, Taraji P. Henson, Pierre Coffin
Other mistake: When dragon Belle Bottom holds him up to her face and says "and now you're gonna pay.", there's no reflection of the terrified Gru in her eyes.
Belle Bottom: Oh, sorry. I didn't mean to scare you. Now, WHERE'S GRU?
