The Blue Lagoon (1980)

Continuity mistake: There is a scene in which it is raining quite heavily and Em and Richard are inside the hutch. Richard is playing Pop Goes The Weasel over and over which annoys Em. She stabs him in the foot and he chases her outside. In this scene she is wearing a strapless dress but when he catches her and pins her down on the sand she is wearing a lacey jacket (she didn't have time to change) and there are no clouds or rain. The sand doesn't seem to be very wet either, despite the fact that it was raining heavily a few minutes ago. (00:41:10)

Continuity mistake: After the baby is born, in one scene where it is lying on the bed, it's lying on a blue-green print receiving blanket. In the next shot, the baby is wrapped in a fur or rough cloth material. (01:20:20)

Revealing mistake: When Paddy lays dead on the beach holding a barrel, the kids turn him over and a crab crawls out of his mouth. You then can briefly see his nose move like a rabbit sniffling. Also his pupils are narrow, and a the side of his neck has a pulse. In other words, he is very much alive. (00:24:30)

Trivia: Brooke Shields had to stand in a ditch in some parts of the movie because she was much taller than her co-star.

Trivia: This version was filmed on the same Island the 1949 version was filmed.

Trivia: Melissa Sue Anderson ("Mary Ingalls" in Little House on the Prairie) was initially given the offer to be Em, but she turned it down because she would have to do some nude scenes. Brooke Shields got the offer instead.

Young Emmeline: Mr. Button, there's a cask over hear with stuff in it that smells like the Captain's breath.

Richard: I feel so a funny in my stomach.
Emmeline: Me too.
Richard: My heart's beating so fast.
Emmeline: Mine too.

Richard: What are you looking at?
Emmeline: Your muscles.
Richard: What about them? You're really acting silly lately, Em. Always saying dumb things like that. Always looking at me funny! You're not coming down with something, are you? Don't give it to me.

Question: At the end of the movie, when the ship finds Richard, Emmeline, and baby Paddy in the lifeboat, Richard's father asks if they are dead. A crewman tells him that they are only asleep. Are they really dead and the crewman was trying to spare his feelings by lying to him, or are they really only sleeping?
