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: 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: 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.GalahadFairlight
