Character mistake: Rodney says that one hour in real time would give them months inside the field. This is incorrect because if the ratio of time were 1:250 as stated before, one hour would only convert to 250 hours, which is 10 days and 10 hours.
Stargate: Atlantis (2004)
1 character mistake in season 2 - chronological order
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?
Irresistible - S3-E3
Trivia: Richard Kind who plays Lucius Lavin in this episode also appears as Gary Meyers in the original Stargate movie.
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.
