THX Calvacade (August 29, 2000, May 25, 2001-May 19, 2009)

Nicknames: "Cavalcade", "T-1000-HX", "Sphere of Doom"

Trailer: In a darkly-lit environment, we zoom in toward a glassy light blue sphere, which has clouds rolling and lightning flickering. As the environment illuminates, we see that the sphere is barely hovering over a textured blue floor. Suddenly, the sphere shatters, and the sky is revealed to contain several rolling clouds. The glass then liquefies and gathers in the center. Some lightning strikes it and forms a THX logo. If you look closely while the logo forms, you can see rain pouring down. Then, the environment fades to black as "LUCASFILM", spaced out to fit the width of the THX logo, fades in on top of it and a shimmering blue rectangle (the same one from "Broadway") is drawn clockwise around the logo (like a laser). The logo fades out as the text "Digitally Mastered for Optimal Audio and Video Performance" fades in.

Variants:
 * In late 2005, the "LUCASFILM" text was removed due to reflecting the 2002 split from Lucasfilm as mentioned above; a www.thx.com web address and copyright info now appear at the end of the trailer in place of the Digitally Mastered message.
 * For the scope version of this trailer, the glass pieces look more stretched out.
 * On the DVD release of Terminator 2, a metallic rectangle with the T2 logo carved out appears from the Time Sphere, zooming toward us. Then, the rectangle gets shot into pieces by the T-800 with the shotgun, as seen on the reflection. The pieces then turn into liquid metal like the T-1000 and form the THX logo. After that, the THX logo fades out, and then it contains a message reading "The Best Sound, The Best Picture. You're Watching a THX Certified Feature" appears one by one as each text fades out before the other. Also, the Deep Note in this variant (the Terminator 2 variant) is the same as the Broadway 2000 version. This is also on the Blu-ray releases with some differences: the THX logo fades into the standard logo, the "DIGITALLY" and "MASTERED" (à la Broadway '95) are replaced with "CERTIFIED," and the www.thx.com URL with a copyright notice appears; which served as the basis of Cavalcade. It appears on the Ultimate, eXtreme, initial Blu-ray, and Skynet editions of this film, but not the 2015 remastered or 4K Blu-ray releases.
 * The fictional DVD release of Terminator II exists where it is the same as the Terminator II version, the words "DIGITALLY" was replaced by "LUCASFILM LTD." in the font as part of the Searchlight Pictures logo, and the word "MASTERED" doesn't appear. The last words appear with the URL and the copyright at the bottom.
 * On the DVDs of The Final Countdown, Fox Demo Disc #1, and The THX Ultimate Demo Disc, the logo fades out before we get to the "Digitally Mastered for Optimal Audio and Video Performance" text. The THX Ultimate Demo Disc also has the framing of 1.85:1. However, it is unknown if this is the original theatrical version of that trailer.
 * On the intro to The THX Ultimate Demo Disc menu, as the rectangle is drawn, the logo moves far away to fit room for the menu options.
 * A 4:3 matted version exists - but only for fullscreen DVDs - it has never appeared on VHS.

FX/SFX: The sphere, as well as it shattering, the thunder, the shards liquefying and merging, the blue box is drawn, and the text fading. Just top-notch CGI all around. Both the T2 variant and Cavalcade were both created by Van Ling, a prolific DVD menu creator and visual effects supervisor for several of James Cameron's films, including Terminator 2.

Music/Sounds: First, we hear the sounds of rainfall, and then thunderclaps/electric shocking sounds, followed by glass shattering, then the Deep Note. A laser-like sound is heard as the rectangle is formed.

Music/Sounds Trivia:


 * The sound of the thunderclap heard before the pieces turn into liquid is the same one that was heard from the Dolby "City" trailer.
 * Also, if you listen closely just as the Deep Note starts playing up to when the logo is formed, you can almost hear the Deep Note used in the "Broadway 2000" trailer being mixed together, meaning that this version of it was originally going to be included in this trailer, similar to the Terminator 2 variant.

Music/Sounds Variants:
 * In the T2 variant, music from Terminator 2 is heard which fades into the Deep Note used in Broadway 2000; the sound design and mix are by Gary Rydstrom at Skywalker Sound according to the credits of the T2 Ultimate Edition DVD.
 * In the fictional DVD version of the T2 variant, there is the same variant, but the Deep Note is extended, and there is actually a lightning sound after the rectangle T2 logo is shot into pieces.

Availability: Common. First seen in most THX theaters starting on May 25, 2001 with its debut being on Pearl Harbor. Seen on several THX DVDs such as Star Wars Episode I: The Phantom Menace, Star Wars Episode II: Attack of the Clones, Alien Quadrilogy, From Hell, Re-Animator, The Incredibles, Bayside Shakedown 2, THX 1138 (fittingly enough), the Star Wars Trilogy 2004 DVD set, and X-Men 1.5; in THX theaters, and on the video games NBA 09: The Inside, MLB 08: The Show, and MLB 09: The Show. It's also the intro to the menu of The THX Ultimate Demo Disc. The final appearance of the Lucasfilm byline variant was Star Wars: Clone Wars Volume One, released on March 22, 2005, and the remastered variant with the THX website URL but no Lucasfilm byline appears on the French DVD releases of Ghost Rider, Abandonnée (along with the 13th trailer), Rec, L'Ennemi Intime, L'Orphelinat, Boxers and Pan's Labyrinth (Le Labyrinthe de Pan) (including the HD-DVD). Don't expect this to appear on the theatrical edition discs to the 2006/08 releases of the original Star Wars trilogy, despite the 'THX Optimizer' option being featured in the set-up menu.

Legacy: This logo has a dark atmosphere, but also has very incredible CGI all around and helps assert THX's power as a brand.
