The Truth is Out There
Carter sought to make the title sequence an "impactful opening" with "supernatural images". These scenes notably include a split-screen image of a seed germinating as well as a "terror-filled, warped face". The latter was created when Carter found a video operator who was able to create the effect. The sequence was extremely popular and won the show its first Emmy Award, which was for Outstanding Graphic Design and Title Sequences. Rabwin was particularly pleased with the sequence and felt that it was something that had "never [been] seen on television before."
The premiere episode of season eight, "Within", revealed the first major change to the opening credits. Along with Patrick, the sequence used new images and updated photos for Duchovny and Anderson, although Duchovny only appears in the opening credits when he appears in an episode. Carter and the production staff saw Duchovny's departure as a chance to change things. The replacement shows various pictures of Scully's pregnancy. According to executive producer Frank Spotnitz, the sequence also features an "abstract" way of showing Mulder's absence in the eighth season: he falls into an eye. Season nine featured an entirely new sequence. Since Anderson wanted to move on, the sequence featured Reyes and Skinner. Duchovny's return to the show for the two-part series finale, "The Truth" marked the largest number of cast members to be featured in the opening credits, with five.
The sequence ends with the tagline "The Truth Is Out There", which is used for the majority of the episodes. The tagline changes in specific episodes to slogans that are relevant to that episode. The first of these was "Trust No One" in "The Erlenmeyer Flask". Other examples include: "Deny Everything" in "Ascension", "Éí 'Aaníígóó 'Áhoot'é" in "Anasazi", "Everything Dies" in "Herrenvolk", "Believe to Understand" in "Closure", and "They're Watching" in "Trust No 1".
