Continuity mistake: The middle curtain on the passenger side of the RV is pulled open to different extents (toward the sides) when Drake is snooping around. Depending on the camera's view, maybe a foot of the curtain can be seen to the right. The other views show much more of the curtain, indicating it is not pulled to the side as far (and might possibly be closed). When a larger amount of the curtain is showing, there is also a small section of a pleat partially on the sill. (00:04:00 - 00:04:27)
Continuity mistake: The aerial view of what is to one side of the RV is different from the ground view. From the air, there is a highway with two lanes in each direction with parking along the side, just off the sidewalk where Drake left his bike. From the ground, there is a 3' cement wall and black railing with greenery behind it. A white house (not in the aerial view) can be seen and there is room for a one-lane road, but the white house would have been on the highway if in the aerial view. (00:05:24)
Continuity mistake: There are brown pleated followed by yellow pleated curtains on the driver's side window when Charles takes a sip of coffee. The camera shifts to Steve (in the front passenger seat) who says, "Hey, pop. Thanks for doing this." When the camera returns to Charles (pop), the brown pleated curtain is no longer there but a fire extinguisher is in its place. (00:09:06)
Continuity mistake: When Steve opens the RV window for Olivia, he reaches at the center to unlatch the pane in order to slide it to the left; the right side of the window is still closed or immobile. A little later when Olivia is right next to the window, there is one pane that slides to the left, there is a screen, and the thin aluminium frame is much wider. The curtains are not visible with, perhaps, a token strip of cloth above Olivia's head. (00:10:43 - 00:11:30)
Continuity mistake: The curtains at Olivia's window are largely see-through silk/linen? With a pattern, plus a solid brown short valance with brown/white horizontally striped trim. Next, there are no visible curtains. When Olivia has her upper body slightly out the window, the "thicker" curtains are a solid brown with a pattern and there's no sign of the valance. Olivia is also where the right pane was or would be (varies) and the window is only half open - but not the left pane as before. (00:10:45 - 00:11:45)
Continuity mistake: When the knife goes through Jay's neck, Jay is sitting at the table and his lower right arm, bent at the elbow, is on the table; his body stays upright. Next, Jay has fallen to the side and his head is setting along the window. Later, Jay's head is resting on his right elbow, and his entire right arm is straight across the table in front of him. After death, it is possible Jay's head with the knife through his neck could stay upright, but these TWO new positions are at least one too many. (01:11:57 - 01:22:02)
Continuity mistake: Charles managed to veer right to get out of the out-of-control RV's path. Seconds later, Charles is moving out of the RV's path again. (01:14:30)
