Character mistake: The map has the word Corazon missing the accent: "Corazón". This is so basic grammar that maybe it was done on purpose.
Romancing the Stone (1984)
1 character mistake
Directed by: Robert Zemeckis
Starring: Danny DeVito, Michael Douglas, Kathleen Turner, Zack Norman
Continuity mistake: When Jack goes down the mud slide he loses his hat. In the next shot the hat is back on his head. (00:30:55)
Joan Wilder: You're a mondo dismo.
Jack Colton: I'm... what am I? I'm what?
Joan Wilder: You're a man who takes money from stranded women.
Trivia: The studio was so sure the film would be a flop, they preemptively fired director Robert Zemekis from his next project, "Cocoon," and instead gave the job to Ron Howard. Ironically, the film ended up being one of the top-ten grossing films of the year.
Question: What is it likely that the stone (an emerald, I gather) was worth in 1984 US dollars?
Answer: Any emerald over 1 carat in that beautiful cut and condition would probably go for over 250 million. Real emeralds over 5 carats are rare and the price goes up exponentially after 2 or 3 carats. 305,000 per carat after 5. So yeah that one was probably like 800 or more carats.
