Question: When Phoebe is on the phone with Ray, he mentions that the Ghostbusters fire house is now a Starbucks. In the post-credits scene, we see that Winston has purchased the fire house so the Ghostbusters can get back to business, but the fire house looks like it has been abandoned for several years and no other company ever took it over. Did I miss something here?
Answer: Perhaps nobody wanted to take over the place for a few reasons. Historical purpose, high cost... hauntings.?
Answer: It's been 40 years since the Ghostbusters disbanded, Ray mostly likely passed by the old place and saw a Starbucks there. It has since shut down.
But they left the ghost trap active? Not likely.
Question: Why did Diana destroy the mall's security cameras, and why did she want the little girl to stay quiet?
Answer: At this point in time, her gig as a superhero is not public knowledge, and she wants it to stay that way.
How would that accomplish anything considering there were many people in the mall who saw what happened?
As the other answer indicated, Diana/Wonder Woman wasn't yet known publicly as a super-hero. A video recording is different from eye-witness accounts of what people actually saw or believe they saw. Memories are faulty, they fade, and everyone sees and remembers things differently. Regarding the child, I interpreted it as Diana just motioning in a friendly way for the rather precocious girl to stay put, behave, and quietly wait for her mother.
In my opinion, it wouldn't, and it's just another example of the shoddy writing in this film.
Answer: This was long before the age of superheroes, when everything was normal and meta-humans were just theories in a lab. It was her appearances which stated it all. Remember the tagline, "The Dawn of Justice Begins with Her."
Question: Assuming that the film didn't underperform, would there have been a sequel?
Answer: A sequel is still possible, but PIXAR and Disney say there are no current plans for one. They are open to the possibility but claim to be moving away from a sequel-heavy slate to instead focus on original projects. Although it received good reviews, Onward under-performed at the box office, though that was partially due to the COVID pandemic. A sequel is doubtful, or, if there is one, it could be a straight-to-video DVD.
Question: I do not remember seeing Bill and Ted dressed as women (was that actually them?) get in the telephone booth to go get their wives. Was this explained somewhere?
Answer: That was their wives' future selves I believe.
Question: How did Cecilia get an invisibility suit?
Answer: Cecilia went over to Adrian's house and found another invisibility suit.
Question: How come there was no dedication to Alex Trebek in the credits?
Answer: The movie was completely finished over a year ago. It was the pandemic that delayed it. So it was the finished product that was released.
Question: Why is the movie called Songbird?
Answer: In an article for The LA Times, producer Adam Goodman says: "The reason why the movie is called 'Songbird' is it's about hope. It's about resilience. It's about the strength of the human spirit."
Question: Why did everyone at the baseball game decide to leave upon seeing the meteor descend from the sky?
Answer: It didn't look or act like a normal meteor streaking through the sky and burning up in the atmosphere. It was large, the fiery mass seemed suspended in air, and it was close enough to the ground that spectators, erring on the side of caution, sought shelter.
What does a "normal" flaming meteor look like? How many meteors do you think the people of a small town in upstate NY have seen? Don't know what you mean by "seemed suspended in air." It was passing over and would land miles away, posing zero threat to the people of the town.
Question: At the beginning, Dolittle was scared because a boy broke in his territory, so he says to Chee-Chee, "Possum, play dead." Why does he call the gorilla possum? Chee-Chee is a gorilla, not a possum. Also Possum is not his name nor nickname.
Answer: 'Playing possum' is slang for pretending to be dead, as possums sometimes do that to avoid predators.
Answer: Opossums will go into a state where they appear dead when threatened, thus the term "playing possum." Dolittle was just saying to act like a opossum and play dead.
Question: A helmet that is built to withstand thousands of PSI can really be broken by a few slams with a fire extinguisher?
Question: Since one male from each family in her village is required to report for training to serve the emperor, how is it that no-one recognizes Mulan - especially when she gives in to her chi?
Answer: Although it isn't said (in either this film or the animated original), she reports to a different camp than anyone else in her village. Otherwise, the men would not only recognize her physically but they would know beforehand that Hua Zhou never had a son so the ruse would never work. How she knows nobody from her village will be at that particular camp is never explained in either film.
Question: When David steps on the land mine, the group rescues him by tying a rope around him and pulling while he runs. What exactly does this accomplish? It's impossible to outrun an explosion, much less pull someone to safety at supersonic speed.
Answer: Yes, I think the blast of a land mine usually goes straight up, unless it's a bouncing Betty.
Answer: Anti personnel mines usually have a small blast radius compared to a bomb or artillery shell. If they can pull him away quickly enough he can be clear of the blast.
Question: Why does Costner change the shotgun shells when the shell in the gun looked intact?
Answer: He did not bring the shotgun from Peter's. It was on the Weyboy's porch and the shells in the shotgun had been shot. He put fresh shotgun shells in.
Answer: Ray was probably being sarcastic, and was simply making a general comment about gentrification in the area.
