The Stagate series include SG-1, Atlantis, and the new series
Universe. SG-1 has over all ten seasons and Atlantis was cancelled
on it's fifth season. The producers decided to cancel Atlantis and
proceed on making a Stargate Atlantis movie with the setting taking
place right after the last episode of Stargate Atlantis. Stargate
Universe unlike Atlantis which has a connection to SG-1, will not
have any crossover with SG-1 or Atlantis. It is a totally new story
about a second ancient ship.
