Continuity mistake: In the scene where Parker is shown playing golf on the indoor golf course in RDA, the first time he hits the ball, there are two other balls lying on the course side by side.

Continuity mistake: In a scene in the planning room (where the computer model of Pandora is being studied by Colonel Quaritch and Parker Selfridge), Jake is watching them move the model quickly to find something on it and they show his digital watch which says 2:19.

Continuity mistake: In the scene after Jake was just in his avatar for the first time, he and the Colonel are discussing things around a holographic 3D map. With each shot, Jake's arms change from being straight out holding the edge of the table, to clasped in front of him, with no time to move the position in between. (00:49:30)
Continuity mistake: When Jake is walking up to the Tree of Souls to ask Eywa for help, he kneels and reaches for his braid as if it were hanging over his shoulder when it is lying down his back. The angle changes and it is now over his shoulder. When he stands up as Neytiri tells him that Eywa protects the balance of life, it's suddenly down his back again.
Continuity mistake: When Jake's avatar is running through the garden as he first enjoys having working legs again, he skids to a stop on the loose topsoil in the aisle of the garden. The next shot that shows him wriggling his toes in the soil reveals a pristine path of soil and no evidence of the disturbance his skidding to a stop caused.MovieFan612
Continuity mistake: There is a scene where Jake and Grace are tied up by the natives, shortly after they are cut down, Jake pushes Grace over a log to avoid an explosion, the shot changes to something else, then returning to the log, and we see that he's pushing her again. then the shot continues.fooey
Continuity mistake: In the scene where Jake wakes up from his link and Grace asks him, "Is the avatar safe?" and he replies, "Yeah Doc, and you are not gonna believe where I am," her hand is on top of his shoulder. But as the camera angle changes back and forth her hand switches to the side of his upper arm and back to the shoulder without time to have made the move. (00:48:55)mrspleen
Continuity mistake: (Extended Edition) In the scene we see Tsu'tey badly injured on the ground, he asks Jake to finish him off in the "Navi way". Tsu'tey reaches out for Jake's dagger and Jake assists him in taking the dagger out of the scabbard. In the next shot the dagger is back in Jake's scabbard and a moment later in the third shot the dagger is now out of the scabbard and in Jake's hand. (01:07:05)keiko
Continuity mistake: When Jake tames Toruk, he confronts the Na'vi and speaks to Tsutey. While Jake is speaking to Tsutey, Tsutey's braids are over his shoulder. After Jake says "You are Oloektan," all but a single braid are behind his shoulder. After this, when Tsutey looks at the Toruk in the distance, a braid or two fall over his shoulder, in the next cut no braids are over his shoulder.
Continuity mistake: In the scene where Neytiri is showing Seze to Jake, Neytiri's ponytail changes positions between shots twice. She puts it over her left shoulder as Seze is landing, it's at her back in the next shot of her, then when she says "Ikran is not horse" it's over her shoulder again. (00:58:15)Dusso Janladde
Other mistake: In the scene after Jake first links to his Avatar body and they are getting ready to put the Avatar's to rest, Grace gets the human scientists to 'scat' and shuts two large gates behind them. There is a CGI error with Grace's left hand. Her hand is not holding the gate handle but is pulling it shut anyway.
Continuity mistake: At approximately 15 mins and 15 seconds, Max is looking over the image and info on the activity for the Avatar drivers. When Jake first drives, he is wearing a black "dog tag" with a blue spot.
