Factual error: When they are trying to navigate the shuttle through Eadu, the shuttle abruptly collides with a rock, which causes Bodhi to jolt backwards. If the shuttle hitting the rock had caused the shuttle reduce speed so abruptly, in the way that was shown, then Bodhi would have jolted forwards, not backwards. (00:57:05)
Continuity mistake: At the point of the movie where K-2SO slaps Cassian on Jedha, you can see Cassian cover up with his face to cover his smile, as the entire slap was improvised, then a shot with his hand down, and then back to a similar shot of the first one with his hand covering his face. (00:34:20)
Continuity mistake: When the Rebel fleet arrive at Scarif, they arrive close to the shield gate and the Imperial fleet. However, when Blue Squadron makes their attack run, they are suddenly high above the shield gate. (01:38:05 - 01:38:40)
Other mistake: Director Krennic is shorter than Tarkin in their scene together. Krennic comes up to Tarkin's ears at best. Krennic is also shown to be about the same amount shorter than Darth Vader, roughly coming up to Vader's ears as well. But as shown in A New Hope, Tarkin is considerably shorter than Darth Vader. So by what was shown in A New Hope, Krennic should be much shorter, perhaps coming up to Vader's chest.
Continuity mistake: When Vader appears at the end, the amount of rebel soldiers facing him changes throughout the scene from about 8-12 as Vader makes his way through them.
Continuity mistake: When K is at the control panel he shoots two stormtroopers to his right. He then says stardust and moves his aim slightly to his left and shoots the same two stormtroopers again - the first two stormtroopers have disappeared from the floor.
Continuity mistake: When Krennic is first talking with Galen Erso on his home planet, the coat that Galen is wearing is visibly drenched, presumably from rain water, but later in the scene, when Lyra Erso intervenes, the dampness on his coat is now much lighter. (00:03:30 - 00:05:10)
Continuity mistake: When Baze shoots all the Stormtroopers, he begins walking over to Chirrut. Chirrut is seen placing two hands on the top of his staff, and then puts one hand lower down on the staff, holding it with just that hand. In the next shot, he is suddenly holding the staff with both hands. (00:35:55)
Continuity mistake: After the facility on Eadu is ambushed by the Rebellion, Krennic is escorted back to his ship and looks back at Galen Erso's body. When he looks over, Galen is shown with his right leg completely straight and his left leg at an angle, but when he is next seen, a few shots later, it is now his left leg completely straight and his right leg at an angle. (01:07:35)
Continuity mistake: When Baze points his blaster at K-2SO, Jyn tells him that he is with them. The shot cuts back to Baze and Chirrut, with Chirrut saying "They're all right" and Baze still has his blaster pointing forwards. In the next shot, Baze's blaster is suddenly lowered slightly. The shot then cuts to Jyn and K-2SO and when the shot cuts back to Baze and Chirrut, Baze is now seen lowering his blaster that is now suddenly raised again. (00:36:05)
Revealing mistake: After Jyn has retrieved the data file containing the Death Star plans, Krennic is shown walking in a hallway with two other Death Troopers and pushes a button to open a door. The door begins to open before Krennic actually pushes the button to open it. While his hand is not seen touching the button, the sound of the button being pressed is still heard. (01:51:10)
Continuity mistake: At the start when Andoor meets Tivik, Tivik's coat over his shoulders keeps moving between shots - on both shoulders, then on one, then both, etc. (00:10:05)
Plot hole: Revelations in this film create a potential plot hole in Episode IV, in which Vader says Princess Leia is his only link to learning the location of the Rebel base. In this film, Vader captures the Profundity (Raddus' command ship), which is transporting the Tantive IV in its cargo hold. Vader then watches the Tantive IV fly away with the Death Star plans, leading into the beginning of A New Hope in which he captures that ship. So, the first question is, were there no survivors of the Profundity Vader could interrogate to learn of the location of the Rebel base (assuming the navicomputer has been scrubbed). Even if the entire crew were killed, in A New Hope we see several crewmembers of the Tantive IV have been captured. This film shows that the Tantive IV was at Yavin prior to the battle (evidenced by R2-D2 and C-3PO in the hangar). That then raises the question of why Vader couldn't have interrogated those other crewmembers to learn the location of Yavin as the Rebel base.
Continuity mistake: When Galen and Krennic are talking at the farm, in some shots the wind is very strong, judging by Krennic's cape and Galen's hair. In others there's virtually no wind at all. This changes immediately between shots, there's no time for the wind to swell or fade. (00:03:30)
