Continuity mistake: In the photo booth scene, Face gives Sosa a phone. Later on, after Hannibal had made a call to Sosa to set up a meeting, Sosa sees an incoming phone call from Face, on the phone presumably given by Face. That phone is a Nokia E71, which is a normal candybar phone. But when she receives the call, the candybar phone suddenly becomes a slider phone.
Continuity mistake: When Hiccup first finds Toothless, there is a dramatic shot where the camera pans over Toothless, and his wing briefly obscures his eye, which is open after the wing passes. But look at the tip of the wing. During the shot there is a stretch of rope wrapped around it. In the next shot, the rope is much higher up the wing and not wrapped around it anymore. (00:13:15)
Continuity mistake: When the bus passes Poseidon and he disappears, the people walking near him also disappear. There is an Asian couple walking from left to right across the shot that should have been still there after Poseidon is gone. Sloppy SFX that sort of spoils the effect of a god being able to vanish.

After leaving the customs they walk across a square. The camera now has a big zoom lens attached to it. Statham is not wearing a lens bag. Where did he get that lens from? Also strange is that the lens is set in manual focus instead of automatic. Yet the picture stays focused even zooming in. This is not possible without looking at the screen. Plus the camera is turned off in the close up shot, with the image on the LCD composited in. (00:28:15 - 00:30:45)
Continuity mistake: In the second scene where we first meet ranger Smith he is shuffling with some information pamphlets. When Ranger Jones yells his name he is startled and drops some of the pamphlets, but we can see that the last ones he put in were on their side. When the camera changes shots there appears to be some pamphlets sticking out. Then in the next shot they are gone. The pamphlets change locations between shots.
