Old Wounds - S1-E1
Continuity mistake: When the Krill shuttles land, they park on either side of the entrance to Epsilon station, but when the Orville crew are escaping, the Krill shuttles are gone momentarily (during the firefight), only to return to their proper places a moment later as the Orville shuttle takes off. (00:33:40)
Continuity mistake: Lt. Malloy has his lower left leg amputated in Isaac's attempt at practical humor. When they later find the leg, it's not just a lower left leg, but an entire left leg (upper + lower). So either Malloy regrew half a leg in the course of a single night, or they forgot to tell the prop department to only make a lower leg. (00:26:35 - 00:30:20)
Continuity mistake: When Kelly catches up with Ed after he found her with Darulio, again, Ed starts shouting with his right hand up at his mouth, but in the next side shot it's his left hand. (00:14:40)
Continuity mistake: While in the shuttle bay, Dr Finn and her family are preparing shuttle ECV-197-2. During the rest of the show they are flying shuttle ECV-197-1. (00:01:15 - 00:05:20)
Continuity mistake: Bortus bites off a big chunk of a drinking glass on a dare, but when he and the crew leave the dining table, the drinking glass is intact.
Old Wounds - S1-E1
Continuity mistake: When Gordon starts to unpack his bag, he moves the flap all the way over. When John enters the room, the flap is still down, but in the next shot the flap is sticking pretty much straight up.
About a Girl - S1-E3
Visible crew/equipment: Right after the opening credits, when Dr. Finn tells Bortus, "I will not perform a sex change on a perfectly healthy newborn," the camera pans to the left as she walks to her desk, and the yellow T-mark can be seen on the floor in her office, where Bortus will stand. (00:03:25)
Old Wounds - S1-E1
Character mistake: After Mercer's speech to the entire crew he dismisses everyone except for the senior staff but everyone, including the senior staff, starts walking away as if they were dismissed as well.
Suggested correction: They were walking away, but not as if they were dismissed. The group of senior officers and Mercer are in a completely different part of the room (or possible an entirely different room). Notice the doorway where Mercer is standing. At the beginning, he's in the doorway and it has a white boarder and a 2nd set of doors. Then he's standing in front of a doorway with a blue boarder and no 2nd set of doors.
Continuity mistake: After Bortus bites into the cactus plant, he puts it down on the table twice.
Continuity mistake: When Bortus knocks Kitan into the turnbuckle, her arms slip to the 2nd rope. But in the next shot of her, her arms are now on the top rope.
Continuity mistake: In the opening, Alara takes a bite with her fork held correctly. When the camera shifts to look at the others, it's upside down as she puts it down.
Continuity mistake: When the crew is working to disable the device helping Pria to hijack the Orville, the Chief drills a hole and creates a great deal of metal/material shavings on the top of the device, which disappear. The device is also aligned differently in respect to the components of the Orville's circuits from the Chief's drilling shot to Isaac's probing shot. (00:34:21)
Continuity mistake: The remote control device installed into the Orville's circuits is shown several times through the episode. When Isaac is beginning to send his leads into the device the corners of the right end of the device are about 1/2" - 1" past the intersection of various block shaped components of the Orville's circuits. However, just moments prior, when the device is shown in place in the same circuit, the corners of the right end of the device line up perfectly with the corners of those same block shaped circuit components as evident by the slivers of light shining between the very thin slit formed where the two sets of corners align. (00:34:15)
Continuity mistake: During the cold opening scene, Claire's right hand is alternately clasping Ty's left arm or lying flat on the bed as the camera shots change.
Continuity mistake: When Dr. Finn takes the covers off her son, Marcus, the white sheet is still around his legs. It's gone in the next shot, but back on his legs when she kisses him.
Continuity mistake: Malloy's hand instantly goes from pointing at Captain Mercer to open in the next quick shot while they are in the Krill chapel.
About a Girl - S1-E3
Continuity mistake: While Captain Mercer and Commander Grayson are having drinks and conversing. Mercer holds his glass close to his mouth in the frontal shots, but the glass disappears in the shots over his right shoulder.
About a Girl - S1-E3
Continuity mistake: In the shuttle bay, Captain Mercer and Commander Grayson's distance between each other changes between shots as they watch Bortus and Klyden depart on the shuttle.
Continuity mistake: The Xelayan in episode one has no eyebrows, and her nose marks are between her eyes. In episode 2 she has eyebrows and her nose marks are on the bridge of her nose.
