Character mistake: Nicolas Cage says "first battalion, tenth Marines from Camp Lejeune, North Carolina gunslingers signing out". It was the second Battalion 10th Marines that was called gunslingers, not the first.
Grand Isle (2019)
Directed by: Stephen S. Campanelli
Starring: Nicolas Cage, Kelsey Grammer, KaDee Strickland, Luke Benward
Factual error: The movie is set in 1988, but the hurricane mentioned ("Jodie") is from 1977. (00:15:20)
Continuity mistake: While listening to news about the hurricane and the disappearance, Fancy looks at Buddy working in the lawn. She spots him from the curtains as he tosses away a broken piece, but in the following close-up he picks up the bloodstained board by stepping over the bit he already tossed aside. (00:15:35)
