Question: At the end of the movie, it is not Dana Carvey getting run into by the car, but it is a stunt double, as he has a different style of hair than Carvey. However, even after the take with the car accident, the stunt double is still seen lying on the road in front of the car, even after the take has already finished with the accident. Why does the stunt double need to be there in place of Carvey, being that there is no danger to Carvey in this situation?
Answer: Either consistency with the prior accident shot, or else simply that stunt performers and stand-ins are cheaper than stars, and are often utilised for shots where the main actor doesn't *need* to be physically present - shots from afar, behind, etc. For example the multiple mistakes in the widescreen versions of Friends where it becomes clear the person at the edge of shot who in the original versions was just seen as "the back of Monica's head" for example. Wasn't actually Courteney Cox but a stand-in: https://www.moviemistakes.com/picture174481.
Question: This might be a stupid question, but why did Roxy not show up the town? Was it really just "circumstances beyond her control"?
Answer: My interpretation is that Roxy had always been determined to get away from the town, and pursue a life of wealth and fame. Attending the event would mean visiting the past that she wanted to forget. She was too afraid to go through with it.
Question: Why did Jack and Max try to kill Mason's son Sonny? They have their masks on and there's no way that Sonny would have identified them.
Answer: He survived the first attempt of his family's murder. There's no telling what he saw or heard. As for the masks, the bad guys were taking no chances, security cameras, cell phones and the unexpected eyewitness.
Question: What was in the red backpack that John Ritter was going to give Michael Richards as ransom for Jr, since he didn't have the 100 grand that he promised him?
Question: Was it all a dream to him? Did he have a vision that his life was going to be like that?
Answer: Mike, as advertised, was Mr. Destiny. When Jim Belushi asked him if he was an angel, Mike replied that when Belushi is about to make a decision, he's the little voice in his head that helps. At the end of the film, when Mike tells the teenage Belushi that everything is going to work out, the kid replies, "What do you know?"
Answer: Like "It's a Wonderful Life" he showed him an alternate life of what could have been.
Thanks then Mike the bartender must have been an angel.
Question: When Peyton wakes up in the hospital, images suddenly appear. What exactly is the significance of the light bulb shattering and the little marionette with the huge head supposed to represent?
Answer: It's just psychedelic imagery to try and show his fragile state of mind and how he's losing it. The shattering light-bulb is likely to show that his mind is "shattering" (as light-bulbs appearing above someone's head are often used to signify brains/ideas in fictional, particularly cartoons), and the marionette "dancing" is the first part of the recurring motif in which he sees himself as a "freak." (Which is paid off later when he starts singing a demented song about "Paying five bucks to see the dancing freak!").
Answer: Norman is mentally stable in this film. Connie and Norman fell in love during his institutionalization. After being deemed sane and released, they were married. Norman is afraid to have children because he doesn't want to pass on his psychosis. Connie believes that with proper care, their child won't end up like Norman, and plans to become pregnant.
