Continuity mistake: When the Riddler blows up the Batmobile, if you look closely, you'll see its rear left wheel cap fell off at different angles.
Continuity mistake: In the scene where Robin steals the Batmobile, the first shot of his joy-ride shows twin fins on the rear of the batmobile on 45 degree angles, in the following shots they are all standing directly vertical. (01:02:40)
Continuity mistake: At the end of the film right after Batman has saved Chase and Robin from falling and Two-Face appears on the ledge, you can see that in one shot Chase has lost her shoes and in the next shot she's wearing black sneakers. (01:48:00)
Continuity mistake: When Chris O'Donnell does the laundry and is putting wet clothes on the string, he takes a clothing item and wraps it around his right leg then twists water out of it. When he does this his right foot goes in the air a few inches above the ground but in a closeup to his foot and water falling it is his right foot standing when it should be his left. (00:55:00)
Continuity mistake: At Edward Nygma's party at the Ritz Gotham there is a fountain with a large version of his "box" on top. When Two-Face comes, he shoots the "box" and destroys it. There should be some parts left over but when Batman falls through the ceiling he lands on the fountain and there's no remains of the "box." (01:12:15 - 01:13:30)
Continuity mistake: Right before The Riddler is about to kill Robin and Dr. Chase, his finger changes position on the button on his cane between shots. In one shot it is next to the button but in the other it is suddenly completely covering the button. (01:57:15)
Continuity mistake: In the scene at the circus when the ringmaster announces "The Flying Graysons", Robin's mom is standing on his left side. In the very next shot, she is on his right side. Also, when Robin is doing the "Death Drop", his mom is on his left and his brother is on his right side. After he completes the stunt and he swings back up with his dad, his mom and brother have switched places. (00:32:45)
Continuity mistake: When checking a tape that shows the (fake) suicide of Stickley, Bruce is handed the suicide letter, which was folded in three parts. The next shot shows a clean sheet of paper, with no wrinkles or folds. (00:26:20)
Continuity mistake: In the scene in which Edward is first testing his "box", watch Ed's left shoulder. He goes to turn off the machine, then says his line "What a rush." The shot cuts to Ed's boss briefly. When the shot cuts back to Ed, his left shoulder strap, which was present in every other shot, is missing. He even reaches to take the strap off as he starts to say "A very surprising side effect." Apparently, he didn't even notice that it had fallen off.
Continuity mistake: When Riddler and Two Face are stealing diamonds, the Riddler is holding a large diamond. Two Face comes over to him and produces an even bigger one. However, if you look closely at the shots, the diamond the Riddler holds gets smaller in one cut, and Two Face then pulls out the diamond Riddler was just holding...
Continuity mistake: When Two-Face and his goons are fleeing Nygmatech after their break-in, as they're running down the stairs there are 3 men in identical blue suits running just ahead of Two-Face. In the next shot they're nowhere to be found.
Continuity mistake: When the Riddler and Two-Face are in their getaway van after robbing the jewelery store, the Riddler has his green hat on, but in the next shot, it has switched to a tiara. (00:55:40)
Continuity mistake: When Bruce is reading the riddle about vowels, it starts out "We're five little items of an everyday sort." He pushes the button to read the second part of the riddle. Then when Bruce walks around, the first part of the riddle can be seen again. (01:33:25)
Continuity mistake: When Batman jumps up into the Riddler's lair, he's gone up the outside of the shaft - we see a shot from his point of view right up to the point of entry, and he's right at the edge. But when he jumps back into the shaft, despite not having moved, he's suddenly right in the middle of it.
Continuity mistake: When Nygma is reading his boss' mind he pulls the lever to add more power. The way he holds it differs between shots. (00:20:22)
Continuity mistake: When Edward Nygma meets Bruce Wayne his hair is messed up around his forehead. A shot later it's nicely combed.
Continuity mistake: When Bruce asks the doorman where Dr. Meridian is a man walks down the steps and leaves. Shot changes and he is walking down the steps again.
Continuity mistake: When Bruce wakes up after getting shot in the head by Two-Face, there is a "BW" (Bruce Wayne) on his pillow next to his left ear. But after Alfred asks, "How are you, young man?", the "BW" is gone. (01:35:55)
Continuity mistake: While retrieving the safe from the chopper, Batman tells the bank guard to "hang on." The guard holds on to the chain to which the safe is attached. But as the safe comes back into the vault, the bank guard is holding on to one of the tubular structures of the safe itself. (00:09:35)
Continuity mistake: After causing Two-Face to accidentally blow up a car that had a couple members of his gang in it, with his missile-launcher, Batman speeds by Two-Face with the Batmobile as he is being chased by other members of Two-Face's gang. In one shot the Batmobile is very close to Two-Face, but in the next shot the Batmobile is far away from Two-Face (when he tries to throw his missile-launcher at the Batmobile). (00:49:05)
Answer: It's hard to say for certain. If Bruce had approved of the project, there would have been a lot more volunteers and oversight of its production, which would have alerted Bruce of the device's side effects, at which point he or one of his underlings would order its production to cease. Edward would still feel spurned and motivated to continue his work, but without the resources of Wayne Industries at his disposal, he may have a more difficult time seeing his plan through.
