Continuity mistake: The shape of the emerald varies. When Catwoman gave it to Isis, the emerald had an oval shape but appeared to be round like a ball when Isis was playing with it. When Whale picked up the emerald, it was oval-shaped but also longer and thinner. Several seconds later when Lady Minerva had the emerald in the palm of her hand, it was round; when she set the emerald on the table, it was shaped like a hockey puck. (00:14:18 - 00:22:24)

Continuity mistake: After he exits the limo, the Black Mask's entourage man with the long hair has the briefcase handcuffed to his left wrist. When he is walking up the steps, he is carrying the briefcase in his right hand, until he stops halfway up the steps and the briefcase is handcuffed to his left wrist like it was. (00:03:25)

Continuity mistake: The driveway and area surrounding the house were clear of fog when the 8 men exited the limo, but the background was foggy when Catwoman drove up to the house 30 seconds later. (00:03:00 - 00:03:30)

Continuity mistake: The view from the (unseen) car driving toward the distant house on a hill showed fog well above the pine trees, but when the car/limo got to the house/mansion (10 seconds later), there was no fog. (00:02:17)
