Factual error: When Ray leaves his wife Gina and his car is hit by the truck he should still be in England, but when he is being chased through the streets he is in South Africa, the cops in the car are not in English police uniforms or vehicle, police livery is incorrect, and all vehicles have South Africa plates, not English number plates.
Deliberate mistake: When the kids are about to jump start the trap Phoebe hides behind the school bus door. Half a second later, when the trap opens, she's nowhere to be seen, not even jumping or stepping inside the bus. Then half a second later she has managed to get inside, turn around and protect her head while the bus windows burst. It all happens in real time for their hairs are still fluttering. It sure paces up the scene, but it's really awkward.
Continuity mistake: When Kat and the protagonist have dinner, his hands swap between crossed or not depending on the shot. (00:28:32)
Other mistake: The van used by Cecilia to chase Tom should be damaged because of the crash, but it was not.
Character mistake: The Rufus hologram states that he first brought the phone booth to the Chosen Ones (Bill and Ted) in 1989, referencing events of the original film. While that was the year the first movie came out, it took place in 1988 (indicated by the opening title card and dialogue throughout the movie).
Continuity mistake: At the market, Lee picks out five pieces of fruit (one apple and four oranges?), tears a produce bag off, and walks away. He takes a few steps off-screen, and he is next seen going around an end cap and walking down an aisle, with nine pieces of fruit in the produce bag. (00:01:36)
Visible crew/equipment: While on the Genesis, when Robin finds Frank she asks if he's bulletproof, then Alpha 5 contacts ops to open hatch 26, and as Frank and Robin walk over to the monitor, a white T-mark is visible on the floor. (01:20:40)
Other mistake: In the credits of the movie, the creator of the original comic's name is misspelled as "Bob Macleod" when it should read "Bob McLeod."
Factual error: Real-life Martina Franca is a town in Puglia, at the "heel of the Italian boot." The town shown in the film is the famous San Gimignano in Tuscany. And when Holly "defects" in order to go to the Hill of Tara, her departure point, as seen on Foaly's observation monitor, is the real-life location of San Gimignano. (00:35:50)
Continuity mistake: Kelly was wearing a white thermal top over a white sleeveless undershirt. After he was thrown into the garbage can, his white thermal top was wet against his back, so he was no longer wearing the undershirt. (00:03:54 - 00:05:43)
Continuity mistake: The direction of the desk lamp's flexible neck varies with the camera's angle. Front views of Rodger show the top of the neck aimed toward the outer edge (length) of the desk and rear views of Rodger show the top of the desk lamp's neck pointed toward him sitting at the desk. (01:02:00)
Deliberate mistake: The oval mirror was in a depressed wall yet was able to reflect a window within the adjacent depressed wall. (00:18:23)
Factual error: The pilot is flying from the left-hand seat. Helos are flown from the right side. (01:23:00 - 01:25:00)
Other mistake: Near the car crash site, Dylan is looking toward a large rock or Boulder that has a handprint made out of blood on it and apparently uses this as an indicator of what direction Mara went and then looks for her. However, Dylan could not possibly see the bloody handprint from where he was standing - the handprint is on the opposite side of the rock (visible to viewers). (00:33:14)
Factual error: After Maya Peters is brought into the recompression chamber because of an injury, the timer is shown counting down by hundredths of a second and skips from 1 to 0 without showing 0.99-0.01. (01:24:30)
Continuity mistake: Isaac is wearing tan or khaki pants but the video of him getting "beamed up" to the spaceship shows dark blue pants. (00:18:15)
Factual error: Joel is using a ham radio set to contact his old colony. A shot of the radio set shows it is set to "CW", which is Morse Code, but he is using voice. And the strength meter is on zero. It should be showing the signal strength. (01:24:00)
Continuity mistake: Within a scene, Xanthe's disheveled hair often has a different number of curls/waves (especially on the sides) and the tightness/ looseness varies. Sometimes some strands of curls look like loops sticking out sideways; sometimes her hair looks almost straight on one side. The nature of the curls may vary with front and back views at times. In one scene, she had about three loose waves on the left side of her hair then suddenly it looked almost braided (many waves). (00:07:21 - 00:07:51)
Other mistake: "Sally" the Great White Shark rammed Emma into a rock (or other hard object) underwater and Emma only got a small cut above her right elbow. It isn't clear how fast Sally was swimming, but Emma was rammed with force (and appeared to hit her back). A female Great White Shark weighs about 4,000 or 5,000 pounds, so Emma would be expected to suffer a major (not minor) injury under the circumstances. (00:05:24)
Suggested correction: As one of the principal developers of the simulation engine, Millie recognizes that Guy is a non-player character (NPC) who merely obeys a loop of coded actions, and he's supposedly incapable of acting outside of his code. So, she means that NPCs can't just arbitrarily kiss players. Players can do whatever they want, but NPCs are mindless robots. At that point, however, she doesn't realise that Guy's Artificial Intelligence has evolved to independent self-awareness, allowing him to act outside of his code.

Key's actually says "There isn't a button for that" when Millie brings it up. There would be no way for her to initiate, as her in game actions would be limited to the controls offered.
By the time Millie kisses Guy, we know that the Free City simulation engine was already undergoing Artificial Intelligence evolution, essentially rewriting its own code, allowing Guy (and other NPCs) to achieve independent self-awareness. It follows that Free City was probably rewriting its player code, as well, making all sorts of new and startling functions possible for players and NPCs alike.
