Other mistake: When in the cave, Leia falls and is caught by Han. She tells him that "being held by you isn't quite enough to get me excited." As she is saying this you can see Harrison Ford mouthing her exact words. (00:44:05)
Other mistake: At the end of the movie where they are looking at the headstone of Jake Hobart, the date on the bottom of the stone is April 3 1913, despite dying shortly before the Titanic sank in 1912.
Other mistake: When Clark and Lois are on their way to the diner, the wide shot of their car driving along looked very familiar. In fact, it was footage used in the first movie, where the car was used as part of Lex Luthor's "real-estate" plan and was run on remote control. If you look closely in part II, no one is driving the car yet you hear Clark say to Lois, "Hey, you seem pretty quiet over there...."
Other mistake: The scenes with Flash and Aura in the shuttle are a complete mess. She tells him that the left lever controls direction, the right controls the altitude. When they are passing the planet Aquarius, she tells him to take a left turn over Fridgia. A) They are passing Aquarius at the time, not Fridgia. B) He moves the right lever instead of the left lever. C) The craft doesn't change direction or altitude and even if it had moved left as supposed to, they would have ended up crashing into Aquarius. The scene when Flash wants to talk to Dale is even worse. He pulls down the left lever to dive into Fridgia. It is the wrong lever. Then when he pulls back up, he correctly uses his right hand, but the right lever is already in the up position as seen in the previous shot. (00:42:15)
Other mistake: Near the end of the movie, Dave Speed jumps onto Torpedo's private plane and starts steering it to the ground. The plane is white with obvious red stripes. However, Dave Speed is supposed to lose his super powers when he sees red.
Other mistake: After the state troopers collide with Bob's pickup truck, both vehicles crash into a fire hydrant improbably located alongside a deserted country highway. (01:29:45)
Other mistake: After Lord Buntaro's archery demonstration, Blackthorne comes over to the post which now bears the three arrows shot by the Japanese. In the paper wall behind him a hole can be seen, which is to be the spot through which the arrows have come. but the arrows and the hole do not make one straight line, which would have to be the case if the missiles were to really have arrived from there.
Other mistake: When Justices car gets crushed as is almost triangular shaped, and driving down the road, it shows a shot of Justice cleaning off some dirt from the dashboard. If you look at the hood/bonnet where all the crease marks are from the crash, you can see quite a bit of rust where the paint has flaked off. Considering the damage is only supposed to have just happened, there should be clean metal not rust.
Other mistake: When they are running through the surf and up the beach in North Africa, there aren't any landing craft in the sea behind them. (00:10:22)
Other mistake: When Tommy tries splashing Rosa during their match she hits the ring mat with her chest and stomach yet seconds later she's somehow knocked out. I never saw her head hit after multiple viewings of that scene.
