Question: When Richard accidentally pulls a coin out of his coat pocket, he sees that it's a penny and he is sent back to his own time. After being weakened upon his trip back to the future, why, after what was likely several days to get his full strength back, wasn't he able to return to the past? His mentor told him returning to his own time would leave him weakened but, given enough time to get it back, he could have gone back to the past again.

Question: When Over's wife gets the call about her husband's plane having problems, there is a horse in bed with her and she tells the horse to let himself out. This is the only joke in the movie I didn't understand. Is there anybody out there who got the joke and can help me understand it?
Answer: This is a reference to The Godfather, where a character being intimidated by the Mafia wakes up with his prize racehorse's severed head next to him on the bed. For comedy purposes this is twisted by the movie as an implied sexual relationship, when the horse is revealed to be alive.
Answer: This is an inside joke that Mrs. Over is cheating on her husband with a horse.

Question: Why in the world is Alex, when unmasked at the end, wearing lipstick? Symbolic or something?
Answer: Alex is not the typical one dimensional slasher serial killer, but rather a complex individual with conflicting motivations. The lipstick is a symbol that he is portraying the hurtful people from his past even as he kills them.
Answer: The film doesn't provide an answer (which I think is a good thing). My interpretation is that Alex has somehow absorbed his sister's spirit, symbolically (not literally), and is avenging her death *as* Robin, in a way. Her name is his last word before he dies. A scene was shot but cut which revealed that Robin and Alex were twins. That scene was added back to the television edit of Prom Night.

Question: I think it is the scene near the end when they are singing "Make the world go away", they pan the audience and zoom in on Amy Irving. Is that Arlo Guthrie in front of her? Sure looks like him.
Answer: I think so.

Question: When Bluto was meeting in private with Wimpy, what were they talking about?
Answer: One, Bluto is a bully and threatened him, after all his name is Wimpy. Plus he most likely offered to buy him a hamburger, which he would have paid next Tuesday.
Answer: How did Bluto convince Wimpy to do it?
Answer: To grab Swee'pea, while everyone was cheering Popeye for dunking the Tax Collector.

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?
Answer: The ending is meant to be ambiguous, and is identical to the ending of the original novel on which the film is based. It is never answered whether they are alive or not.
Answer: At the end of the movie, it says they are only asleep. But in the second film (The Blue Lagoon: The Awakening), they say that they are dead. However, the child is not, because he didn't actually eat any of the dead and buried berries. Then they named the baby Richard because that was the first word baby Paddy could say. He probably said it a lot, so they thought that was his name.
Answer: He was no longer able to put everything out of his mind, which was a requirement to successfully time-travel. He was distraught and unable to focus enough mentally. He stopped eating, and as time went on he became weaker and weaker.
