Revealing mistake: When Marisha waves the flags to start the race, you can see the road behind her is clean. But once the cars get past her and it cuts to a view from in front of them, suddenly there are skid marks on the road in the lane where the '89 Batmobile is. The marks are not lined up with the car at that moment, so they are from previous takes of the race. (00:08:00)
Revealing mistake: As the Batmobiles are supposedly drag racing at very high speeds down a road, some shots show a camera crew reflected in the fender of the 66 Batmobile, keeping up with the two super speeding cars, that are depicted to be drag racing at top speeds... In a pick up truck. (00:08:10)
Revealing mistake: After the race, Marisha, Damian, and Andy go to the guy with the laptops to see the photo finish. As the camera shows the two laptops, you can see they are not even turned on, the screens being totally black, only showing the reflections of the things around it. It cuts to a different closer angle showing the guy typing on it, yet the screen is still totally blank. (00:08:25)
Revealing mistake: When the simulation starts, Wolverine is shown stabbing a guy with his claws. There is a blood splat on the wall, but there is no blood on Wolverine's claws. (00:02:15)
Revealing mistake: When Gambit hits Nightwing with exploding cards and sends him through the wall, the bricks of the wall are obviously not bricks at all. It's some sort of set wall designed to easily crumble as the actor goes through it. (00:03:20)
