Other mistake: McKay and Jackson enters a room and runs into 2 armored figures, Jackson eventually reveals that they are empty suits, however in every shot shot from behind the suits, the suits are constantly moving, as if they are hanging on strings.
Stargate: Atlantis (2004)
1 other mistake in season 5
Starring: Jason Momoa, David Hewlett, Joe Flanigan, Rachel Luttrell
Factual error: Anytime a character fires a missile at an airborne target, it's invariably from an M136 antitank launcher. The M136 is designed to hit relatively slow moving ground vehicles and is useless against fast moving airborne targets. (This is because used M136 tubes can't be reloaded and are very cheap to use as props).
Dr. Rodney McKay: Did I mention that I know almost everything about almost everything?
Trivia: The show's two hour premier broke the SCI-FI's ratings record by attracting over 4.2 million viewers. It was also the most watched cable program that day.
Question: When the ancients return to Atlantis they are greeted by 2 star general O'Neill but later in that episode and the part 2 episode he only had one star on his uniform. This same thing happened in a SG-1 episode when Dr. Jackson became a prior for the Ori.
