Continuity mistake: Jail cells have a rectangular slot with an outward flat extension for setting down food trays. The guard checks cells after "lights out" and there are no flat extensions for trays. (00:23:50 - 00:24:35)
Continuity mistake: Jackie holds her pen as she takes notes. Next, her pen is set on the legal pad and her hands are on her lap (below the table and pen). The camera returns to Jackie, and she continues to hold the pen as she takes notes the whole time. (This allows for other questionable variations that could occur off-screen, if enough time.) (00:38:57 - 00:39:29)
Continuity mistake: The gingerbread man cookie falls into the coffee cup, and the top is barely below the rim. Looking into the cup, the top of the cookie is much further down but does not fall this fast. The coffee cup is about half-full. Jackson takes a drink. The cookie does not interfere with the flow of the coffee into Jackson's mouth. When Jackson lowers the cup from his mouth, there is no visible cookie. (00:08:20)
Continuity mistake: The man picks up his duffel bag and swings it over his shoulder, but does not use its strap. He runs through the woods, and the strap is over his shoulder. Just before he runs onto the beach, he swings his bag over his shoulder, as if he does not use the shoulder strap in the woods. (00:01:40)
Continuity mistake: Ava sees the stack of mail on the table. She sweeps her hand (fingertips and envelopes are off-screen), as she slides the top envelope closer. Ava picks up the top envelope, as if her hand sweep does not move any of the envelopes (and serves no purpose). (00:05:48)
Continuity mistake: Gabby's head is turned to her left. She turns to her right, but she is instantly back to her head turned to her left, as if she never turned her head. (01:22:57)
Continuity mistake: At the clothing rental store, Maigret puts the box with the victim's bloodied dress on the counter. He leans against the counter with closed fists, but in the next shot, we see Gérard Depardieu leaning with his open hands flat instead. (00:17:00)
Continuity mistake: The group come across an outpost only to find the person inside having been brutally killed and skinned by Indians. A shot from the door shows Will sitting on his horse hunched over, staring into the cabin in shock. When the camera cuts to a close-up of him, his body is now at a different angle, his arms are in a slightly different position, and the light is hitting his coat and hat from a different angle.
