Other mistake: When Diana opens the email sent by Bruce, the attachment containing the LexCorp Meta Human Research videos lists the file size of the entire attachment as 24MB. However, the file sizes for the four video files inside the attachment are listed as 12MB, 503MB, 32MB and 214MB. This equals to a minimum file size of 761MB, greatly exceeding the 24MB listed as the attachment file size.
Continuity mistake: After Superman and Doomsday kill each other, Superman is lying in Doomsday's hand with his eyes wide open. When Batman walks over to Superman and folds his arms over his chest a couple of shots later, Superman's eyes are now closed.JRambo299
