Stargate: Atlantis: First Strike

"First Strike" is the 60th episode and the third season finale of the science fiction television series Stargate Atlantis. The episode originally aired in Canada on February 5, 2007 on The Movie Network, and subsequently aired March 14 on Sky One in the United Kingdom, and June 22 on the United States Sci Fi Channel. It was written by executive producer Martin Gero, and directed by Martin Wood. The episode is the first of a three-parter, in which the new Earth ship Apollo arrives at Atlantis to conduct a preemptive strike against the Asurans before they can launch a fleet to attack Earth. "First Strike" was a beginning to a new direction for the series. It aired alongside "Unending", the series finale of Stargate SG-1. At the time it was considered the best episode the producers have done, and featured one of the longest visual effects sequences in the series. The episode earned Stargate Atlantis the strongest ratings since the mid-season hiatus, and was generally well received.
