Edward Nygma goes from a huge prototype model of his device to a small streamlined gadget in the space of a single cut scene. How did he shrink down his life's work in such a short time? It seems like something like that would have taken at least 6 months to do the re-engineering and build the company infrastructure to produce it. Wouldn't this have aroused the suspicion of the worlds greatest detective? I mean, what kind of crazy industrialist builds his headquarters on an island in the middle of a river? [A criminally insane one. Most all of Batman's villians seem to get smarter and more creative once they go insane.]

Batman enters the Riddler's throne room through a small hole in the floor, and it closes after he enters. Then the Riddler introduces Chase and Robin, and two holes like the one before appear under each tube. Nygma says Batman can't save them both. BUT, when Batman jumps to save them both, half the floor has disappeared! Why are Chase and Robin's holes connected, if the Riddler planned not to let Batman save them both? And where did the big big hole came from? It can't be due to the explosions - it's a nice neat line all the way around. The Riddler hasn't pressed the button on his cane yet either. [The big hole came from the Riddler's mind since he can read men's minds, and as is stated by Batman he can make them see whatever he wants. The connected holes of Chase and Robin are to trick Batman into thinking that there is actually a floor there. If you look closely before the floor disappears you can see it blink out and fuzz away like a computer image.]

In a gas turbine engine, as installed in the Batmobile, a full forward position on the fuel control lever(commonly called a throttle or power lever), is full power. During the chase scene before he escapes up the side of the building, he pushes the lever forward to slow down, and pulls it back to speed up. This would be extremely confusing to a pilot versed in turbine engines (the Batwing from the first Batman movie). [Only one guy needs to know how it works, and that's Batman. Since he built it, he can make the handle go any way he wants to suit him.]

The big question at the end of the film - Does Edward Nygma know who Batman really is? Once they see that Nygma is crazy everyone is confident that Batman's real identity is a secret. Unfortunately, they don't take into account Two-Faces large team of henchmen who stormed Wayne Manor, all of whom (presumably) now know that Bruce Wayne is Batman. Less than half of them were captured by Batman's underwater net, leaving several to spread the word of Bruce Wayne's secret identity. [While they did indeed storm Wayne's home, Nygma was the only one to actually find and enter the Batcave. There's a decent chance that none of the henchmen were aware that they were necessarily attacking Batman's home, just some billionaire playboy.]

How did Bruce Wayne get planning permission to lay miles of metre-wide metallic pipe complete with flourescent lighting, and which presumably needs some sort of regular maintenance, beneath Gotham's busiest streets, skyscrapers, office buildings, traffic spots etc. The logistics involved do not bear thinking about and even if he used city hall connections and called in favours from old friends (which he would certainly be able to do being a billionaire businessman) he would need a bloody good reason to rip up half of Gotham's streets. He obviously didn't say it was so he could get to the batcave quickly so how on earth did he do it without anyone asking awkward questions? Surely just hiding a batsuit and 'spare' batmobile in a vault in the basement of Wayne Enterprises would be easier? [Tunnels or pipes can be laid without need of tearing up streets. Knowing from previous movies Batman's love of the sewers, it is possible that the tube goes through along unused section, or it used to be a section of sewer pipe. We aren't given many details about this particular contraption, but is it very possible that it could exist.]

Riddler's big riddle for Batman is "Who will he save...Chase or Robin". How did Riddler know Robin exsisted? Didn't Dick just put on the robin suit 5 minutes earlier? [You would think that he would get this information when they captured Robin.]

Early on in the film, Bruce Wayne descends to the Batcave in a pod that travels at a very high speed (the display projected onto his face proves this), and the journey takes about 10 seconds, whereas later on the Cave can be reached by way of a short flight of steps (Dick Grayson falls down them). That must have been a very long route taken by the pod. [The pod was coming from Wayne Enterprises (across town one would assume) and NOT from Wayne Manor.]

When Chris O'Donnell is doing his laundry he is wearing a black t-shirt but when he puts an item of clothing onto the line it is moved along the line by someone wearing a grey sweater. When the camera goes back to Chris O Donnell he is still wearing the black t-shirt. [What you are seeing is really Chris O'Donnell's foot, not his hand. He is doing his laundry in a "unique" way by kicking it down the line. As you will see, he is wearing gray sweatpants.]

More curiosity than goof - all throughout the movie, Batman keeps nagging Robin that he should not kill Two-Face - it won't bring back his parents and will make him kill again, and again... But at the end of the movie, Batman has put an ample amount of change in his pockets (utility belt?) just to fool Two-Face to grab for his coin amongst the change, and...well, you know what happened. What kind of example is this for Robin? Surely if he could reach for his change, he could have reached any number of devices from his utility belt to contain, not kill, Two-Face. Also keep in mind that Harvey Dent (who became Two-Face) was a friend of Bruce Wayne, which adds to the coldness of his death. [The coin trick wasn't meant to kill Two Face - just distract him so Batman could capture him. However, Two Face panicked and did himself in].

As Chris O'Donnell (Dick Grayson) packs to leave Wayne Manor, Alfred calls him Master Chris instead of Dick. [He calls him Master Grayson].

Near the end of the movie, the Riddler gives Batman two choices; he can save the woman he loves, or he can save his partner. You can clearly see that both of them have tape over their mouths. Batman saves the doctor, and peels the tape away from her face. Then the camera cuts to Robin, and he has no tape over his mouth. If Batman didn't save him yet, and Robin's hands are tied, where did the tape go? [It's not tape, it's some sort of cloth, tied at the back. As he's falling, we can see that it's fallen around his neck].

In the first Batman movie Harvey Dent was black, but this time he's played by Tommy Lee Jones who is white. [This keeps being submitted over and over again - I really don't think it's valid, as it seems to be based on his skin colour, which shouldn't matter any more than other distinguishing characteristics. If this is a "mistake" then it's also a mistake that Batman used to be played by Michael Keaton but in this film was played by Val Kilmer - just a different actor playing the same part, so what's the big deal?]
