Corrected entry: In the closing scene where the Operative tells the Alliance soldiers to stand down, one of the soldiers (almost out of frame) lowers a set microphone.
Corrected entry: After Serenity crash lands on Mr. Universe's planet, Kaylee says she can rig the door so it won't open once it's shut. All points say she has done this. However, once Mal comes back, he asks where River is. The door which is supposed to be shut for good opens dramatically to show River standing in the middle of dead Reavers just in time for the wall to fall down. River is nowhere near the door, and no one inside the room has gone anywhere near it either, so regardless of just how permanently that door was sealed, nothing's caused it to open.
Corrected entry: During the final fight scene between Mal and the Operative, Mal breaks his back (or possibly just dislocates his shoulders). Yet, a few scenes later they're talking and he shows no signs of injury whatsoever.
Correction: After the final fight between Mal and the Operative, Serenity has been completely rebuilt. This couldn't have happened overnight. That's plenty of time for the Operative and Mal to heal from their respective injuries.
Corrected entry: In the pilot of Firefly, River seems shocked to see Simon when she wakes up from cryosleep. In Serenity, she sees Simon before going into cryosleep, so she should remember. One could argue that due to her mental problems she simply forgot, but River's memory has always been extraordinary, even in terrible circumstances.
Corrected entry: According to Joss Whedon, people in the Firefly universe speak only English and/or Chinese (see Special Features and the movie's subtitles), and yet, the writing we see everywhere is Japanese (there's a difference between Japanese and Chinese script; it's obvious for those who know).
Correction: Joss Whedon misspoke; this is not a movie mistake.
Corrected entry: In the opening sequence, the movie shows Simon Tam personally rescuing River; however, in the pilot episode of the series he states that he funded a group to sneak her out to him.
Correction: So he lied about the details. These are people who he's only just met, has no way to know whether he can trust, he's hardly going to want to admit to having personally broken into a secure facility, so he lies. It's quite understandable that he would be somewhat evasive.
Corrected entry: During the trading station robbery, the man who opens the safe and says "You're independents, eh?" is voiced over by Firefly creator Joss Whedon.
Correction: Actually that man said his own dialogue with his own voice. Joss's voice is what you hear coming from down the stairs in the "hidden" vault.
Corrected entry: During the bank robbery scene, down in the vault. Just after Jayne shows up to warn Mal of the reavers, count the people moving behind Mal. Zoe was already in the vault and Jayne went to join her. Then Jayne runs behind Mal out of the vault, followed by someone else (I think it was Zoe) and then Zoe again. Though it's unclear, three people exit behind Mal after only two went in.
Correction: There was a security guard already in the vault. It's him running out.
Corrected entry: On Miranda, when they do the spiral shot around River during her "they're everywhere" speech, a camera person in white is visible in the window to Wash's left. (01:13:30)
Corrected entry: When Shepherd places his hand on Mal's ear and face, it leaves a large bloody mark. The mark vanishes for a few shots, then returns.
Correction: No, it doesn't. The shadows on his face are just really sharp and dark so you can't see the stains really well, but they're there. The position of the stains (more on the neck and ear, actually) puts them out of straight camera range, too.
Corrected entry: In the scene near the beginning when the Operative is investigating the escape of Simon and River, he is reviewing the recording of them escaping from the facility. During his conversation with the doctor, he changes the recording to show the doctor's and Simon's conversation, pointing out the phrase "Key members of Parliament." Later, after he has killed the researcher, the Operative goes back to the recording and it's back to Simon and River escaping, seemingly without him changing it back.
Corrected entry: After the reavers first show up in town, there is a harrowing chase back to the ship. At the finale, it's Mal and friends heading straight for the reavers. Serenity shows up in the middle of them with the cargo doors open. The crew slides neatly into the ship and to safety. A few moments later, a reaver, along with the top of his ship enters through the same door. The mistake here is that the reavers were going the opposite direction. Not only would the reaver ship just scrape the bottom, it would have had to instantaneously change directions in order for the top to be shorn off like that. Basically, for what happened to work, the reavers would have had to have been directly behind them instead of head on, as they were.
Correction: Serenity does not appear in between the hovercraft and the reaver ship. It appears behind the hovercraft which is "swallowed" by Serenity from behind. Serenity's cargo doors are located on the front of the ship, not the rear, as this entry seems to imply.
You are both right. The hovercraft was being chased by the reaver ship. Then Zoe, the hovercraft pilot, spun around heading towards the reaver ship. At that point they were moving in the same direction as Serenity, which swooped in behind the hovercraft, and Serenity's front facing docking bay opened and "swallowed" the hovercraft backwards, easing any damage that might happen to the crew. The reaver ship was shorn off correctly.
Corrected entry: When the Operative is reviewing the computer file on Mal, one of the notes reads "Awarded Valor Commendation: Battle of Serenity Valley." Since the Battle of Serenity Valley was the decisive battle of the war, which the Browncoats lost, who awarded him the commendation? The Browncoats had surrendered, so they were certainly in no position to hand out medals, and the Alliance would surely not have given Mal an award for fighting them so tenaciously.
Correction: The battle of Serenity Valley lasted over two months - there would certainly have been lulls in the fighting during that time as the combatants resupplied, regrouped and so forth. Mal went from commanding a single squad in the battle to being in charge of over two thousand soldiers, keeping their morale up and keeping them in the fight. Given his heroic actions, the Independent commanders obviously decided to award him the commendation for valour during one of those lulls.
Correction: I've watched this scene multiple times and I cannot see a microphone anywhere. Every soldier is holding a gun and nothing else. Where abouts is this microphone? "Almost out of frame" isn't very precise.
