Best sci-fi movie mistakes of 2016
Continuity mistake: It was briefly stated in the second film that the T-Virus was created by Dr. Ashford to cure his daughter Angela and that the Red and White Queens were based on her. This movie contradicts that by suggesting that Dr. Marcus created the T-Virus to cure his daughter Alicia, and that the Red/White Queens were modeled after her. While the rest of the movie stays true to the continuity of the previous films, this rather obvious ret-con is still a major continuity gaff.
Plot hole: When the inspection team goes into the Rogue One shuttle and then the Rebel team comes out of the shuttle in the inspection team's disguise, no one near the landing pad or in the building notices that two stormtroopers have disappeared from the group, the Imperial Officer has grown a beard in less than 5 minutes, and an Imperial Droid has come into the group.
Factual error: When the new president talks to the world on shortwave radio, some kids are adjusting a TV antenna in one shot. Shortwave radios wouldn't work with TV antennas, they use two significantly different frequencies. Shortwave is a much longer wavelength and would require larger antennas to work.
Other mistake: When Amy Adams leaves the spacecraft for the final time she is met by Jeremy Renner who throws a blanket around her shoulders. As he does so, the blanket gets caught on something out of view top-of-frame (presumably a boom mic) and he has to tug at it to free it. This was part of one long take in fading light and given the amount of background action going on it was presumably too difficult or time consuming to re-shoot.
Continuity mistake: When they are at Sarah's house, the boy's father tells her to go outside and ask Lucas to pull the van around back. When Sarah walks to talk to Lucas her long braided hair is tucked into her shirt and her arms are crossed. In the next shot when the camera comes back, her hair is on the outside of her shirt despite her arms still being crossed.
