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)
1 character mistake
Directed by: Stephen S. Campanelli
Starring: Nicolas Cage, Kelsey Grammer, KaDee Strickland, Luke Benward
Factual error: Most of the action is set in 1988. The prologue with the two little girls is set before or during that year, but the girl scouts are selling "Thindulgent Sandwich cookies", by Sheila G, a brand established after 1992. (00:01:55)
