Continuity mistake: Moving out to Sera, Ben is packing his things in a motel. You can see a half full glass standing on a bed table on his left.

Eventually he is drinking from a glass full of alcohol.
Continuity mistake: When the incomplete second EAM is shown in the movie for the first time, its subject line states "nuclear missile launc..." However, when this same message is finally received at the end of the movie the subject line states: "terminate launch all missiles". If the first one had been consistent with the second this would have made quite a difference. (00:55:45 - 01:45:25)
Revealing mistake: When Two Face and Riddler enter Wayne Manor, and knock Alfred down. Alfred, unconscious, pushes the dinner tray aside, so the thugs can carry him into the closet. (01:27:55)

Continuity mistake: When Deebo is riding his bike to Craig's house the first time, one shot shows Deebo nearly on the driveway. Just then Smokey and Craig remove all their valuables. If this were true, Deebo should have seen these. But then in another shot, Deebo's bike is shown just coming onto the driveway. In that amount of time, Deebo should have been further up the driveway.
Other mistake: Whenever Helen Hyde turns back into Richard Jacks, none of the clothes ever seems to rip or stretch - they both have different body types.
