The Magnus Beam - S1-E11

Revealing mistake: Crane overcomes his guard in a fistfight by hitting him in the face three times. But if you watch closely, it's apparent that not one of his blows connects. He "strikes" the air above the man's head all three times. (00:32:00)

Long Live the King - S1-E15

Revealing mistake: One of the saboteurs sneaking into the palace keeps looking up at someone off camera. He's not watching the door he just entered by, so who's he looking at in what should be an empty corner of the room? (00:00:30)

The City Beneath the Sea - S1-E2

Revealing mistake: On the beach, Molina is petite, thin and small-chested in her wetsuit. Underwater, she mysteriously gains several pounds, bigger muscles and a much larger bust, thanks to a poorly-matched stunt double. (00:12:00)
