&amp;#039;&amp;#039;&amp;#039;Season four&amp;#039;&amp;#039;&amp;#039; of &amp;#039;&amp;#039;[[Stargate Atlantis]]&amp;#039;&amp;#039; began airing on September 28, 2007 on the US-American [[Sci Fi Channel]]. The fourth season concluded after 20 episodes on March 7, 2008 on Sci Fi. The series was developed by [[Brad Wright]] and [[Robert C. Cooper]], who also served as executive producers. [[Amanda Tapping]] ([[Samantha Carter|Col. Samantha Carter]]) joins the cast as a regular for 14 episodes, [[Jewel Staite]] (Dr. [[Jennifer Keller]]) was a recurring character for eleven episodes, while regular cast member [[Torri Higginson]] ([[Elizabeth Weir|Dr. Elizabeth Weir]]) was a recurring cast member for four episodes. Other season four regular cast members include [[Joe Flanigan]], [[Jason Momoa]], [[Rachel Luttrell]], and [[David Hewlett]].&lt;br /&gt;
&lt;br /&gt;
==Production==&lt;br /&gt;
&lt;br /&gt;
With the season premiere, {{ep|Adrift}}, [[Amanda Tapping]] replaces [[Torri Higginson]] in the opening credits sequence, with [[Paul McGillion]] no longer appearing. This marks [[Amanda Tapping]]&amp;#039;s first appearance as a main character on Atlantis. It also marks the only time an actor has appeared in the opening credits of both &amp;#039;&amp;#039;[[Stargate SG-1]]&amp;#039;&amp;#039; and Atlantis. [[Christopher Judge]] has a [[w:cameo appearance|cameo appearance]] as his &amp;#039;&amp;#039;[[Stargate SG-1]]&amp;#039;&amp;#039; character [[Teal&amp;#039;c]] in {{ep|Reunion}} and guest stars in the episode {{ep|Midway}}. Judge is the last original &amp;#039;&amp;#039;Stargate SG-1&amp;#039;&amp;#039; regular to appear on Atlantis, as the other three characters in the original SG-1 team all appeared in Atlantis&amp;#039;s first season, as did other SG-1 characters [[Hank Landry]] and [[George Hammond (Home hallucination)|George Hammond]]. Of the three other SG-1 regulars (namely [[Cameron Mitchell]], [[Vala Mal Doran]] and [[Jonas Quinn]]), Mitchell and Vala visited Atlantis in the SG-1 crossover episode {{ep|The Pegasus Project}}. [[Jodelle Ferland]], who plays Princess [[Harmony]] in the episode {{ep|Harmony}}, previously appeared in the episode {{ep|Flesh and Blood}} in Stargate SG-1 season 10 as a young [[Adria]]; and [[Crystal Lowe]] previously appeared in the episode {{ep|Emancipation}} in season 1 of Stargate SG-1.&lt;br /&gt;
&lt;br /&gt;
== Release and reception ==&lt;br /&gt;
&lt;br /&gt;
In September 2007, unfinished versions of {{ep|Adrift}} and {{ep|Lifeline}} were leaked onto the internet. Shortly after, fans who used [[w:iTunes|iTunes]] to download &amp;quot;Adrift&amp;quot; discovered that they had in fact purchased {{ep|Doppelganger}} instead, three weeks before it was set to premiere on [[Sci Fi Channel]] in the USA. The mix-up probably comes from the fact that &amp;quot;Doppelganger&amp;quot; was the first episode of the season to be filmed, and thus carries an internal production number of 401 at the studio.&amp;lt;ref&amp;gt;{{cite web |url=http://www.gateworld.net/news/2007/09/doppelganger_gets_early_itunes_r.shtml |title=GateWorld - &amp;#039;Doppelganger&amp;#039; gets early iTunes release |accessdate=2008-11-14}}&amp;lt;/ref&amp;gt; Late in the season, {{ep|Midway}} was another episode that was mistakenly released by iTunes several days before its airdate. {{ep|Be All My Sins Remember&amp;#039;d}} received a rating of 1.4&amp;amp;nbsp;million viewers, the highest rated episode in the fourth season. It was also the US Sci-fi Channel&amp;#039;s 2nd highest rated show that week: the 1st was an SF TV-movie, &amp;#039;&amp;#039;[[w:Beyond Loch Ness|Beyond Loch Ness]]&amp;#039;&amp;#039; (which had a rating of 1.7&amp;amp;nbsp;million), which happened to star Atlantis actor [[Paul McGillion]] and SG-1&amp;#039;s [[Don S. Davis]]. Stargate Atlantis, Season 4, has been aired on the following channels: Sci-Fi Channel in the USA, TV6 in Sweden, and Sky 1 in the UK.&lt;br /&gt;
&lt;br /&gt;
&amp;quot;Adrift&amp;quot; earned an [[w:Emmy|Emmy]] nomination for &amp;quot;Outstanding Special Visual Effects For A Series&amp;quot;,&amp;lt;ref&amp;gt;{{cite web |url=http://www.gateworld.net/news/2008/07/iatlantisi_gets_visual_effects_e.shtml |title=GateWorld - Atlantis gets visual effects Emmy nomination |accessdate=2008-11-14}}&amp;lt;/ref&amp;gt; and &amp;quot;Best Visual Effects&amp;quot; for a [[w:Gemini Award|Gemini Award]].&amp;lt;ref name=gemini_nom&amp;gt;{{cite web |url=http://www.gateworld.net/news/2008/09/iatlantisi_nominated_for_four_ge.shtml |title=Atlantis nominated for four Geminis |accessdate=2008-11-14}}&amp;lt;/ref&amp;gt; [[Jewel Staite]] has been nominated for a [[w:Gemini Award|Gemini Award]] in the category of Best Performance by an Actress in a Continuing Leading Dramatic Role for her performance in {{ep|Missing}}.&amp;lt;ref name=gemini_nom /&amp;gt; [[Alan McCullough]] has been nominated for a Gemini Award in the Best Writing in a Dramatic Series category for his episode {{ep|Tabula Rasa}}.&amp;lt;ref name=gemini_nom /&amp;gt; {{ep|The Last Man}} has been nominated for a Gemini in the Best Achievement in Make-Up category.&amp;lt;ref name=gemini_nom /&amp;gt;&lt;br /&gt;
