'''Trivia''': The nicknames for some of the early THX trailers given by Lucasfilm, Ltd. derive from the earliest Oscar-winning pictures, like ''Wings'', ''Cavalcade'', and ''Cimarron''.

'''Music/Sounds''': A synthesized crescendo sound effect known as "Deep Note". It starts off with a group of 30 descending synthesized voices reminiscent of the sound of an airplane flying. Each voice moves slowly and randomly in a frequency sweep between 200hz and 400hz. This part of the Deep Note then repeats, and eventually, the voices proceed to their target notes, a drastic change of three octaves. The lower notes grow deeper, and the higher voices grow more shrill, becoming an ascending dramatic sound until the sounds stop in one pitch. Three voices are heard per note, slightly detuned. Two more voices are heard in the bass. It was coded by James Andy Moorer.

'''Editor's Note''': The introduction of the infamous THX logo. It's a simple effort, but nonetheless a very effective one as well, mostly thanks to its musical soundtrack, the Deep Note. It is probably one of the most infamous movie sound marks in history, thanks to its often frightening nature for younger viewers.

LUCASFILM LTD.  

*1995 A: The audio was remixed digitally in [[Dolby|Dolby Digital]], [[DTS]], and [[Sony Dynamic Digital Sound|SDDS]] with then-new technology (with the latter system even having a special end variant).

*1995 C: Both the audio and the trailer is shorter than the standard 1983-1997 theatrical version. The audio (in this, and both 1995 A & B variants) is also in +2 higher (on VHS & LD; +3 on PAL releases), or -1.5 lower on DVDs.

*From 1997-2003, an alternate version appeared where the original text above (and above only) the THX logo was "LUCASFILM LTD." This appeared only on Buena Vista releases until it was officially replaced with the "DIGITALLY MASTERED" (as described above) text when Lucasfilm Ltd. spun off THX into its present-day company.

*For the Dell PC's THX Picture and Sound Optimizer disc, "The Audience is Listening" tagline is replaced with "Your Dell PC is THX Certified". "Dell" is in its usual font. "SOUND SYSTEM" is replaced with "BEST PICTURE. BEST SOUND." Afterward, the URL www.thx.com is seen with the trademark and a disclaimer at the bottom.

*On the ''Apollo 13'' DTS LaserDisc as well as the Japanese LaserDisc of ''Star Wars Episode I: The Phantom Menace'' (Japanese release) and the LaserDisc release of ''Con Air'' (in their respective AC-3 soundtracks), the Deep Note on the THX LaserDisc logo is the -1.5 pitch Deep Note like the DVD/Tex.

*On ''The Lion King'' Deluxe CAV Letterbox Edition, ''Clear and Present Danger'', ''Strange Days'', ''Die Hard 2'' and ''True Lies'' (in their respective AC-3 soundtracks), some LaserDisc prints of the ''Stargate'' widescreen AC-3 release and ''Species'', the Deep Note on the THX LaserDisc logo is a short version of the 1983 Deep Note (blending in with the fade-out of Dolby Ghost Train), though other prints use the +2 pitch Deep Note. (likely corrected copies as the early prints for the former were infamous for audio mixing issues).

*On the 1994 LaserDisc of ''Night of the Living Dead'', the Elite Entertainment logo fades to the THX LaserDisc logo.

'''Music/Sounds''':

*The HD version, or "Broadway Classic (Restored)," has the remastered Deep Note used in the "Science of Sensation" trailer.

*On international prints of the 2000 DVD of Aliens, there are some unique sound variants:

*** However, the Japanese audio track features the VHS pitch of the Deep Note (E key).

** The VHS variant of the standard logo made a surprise appearance on Disney Channel airings of ''Monsters, Inc.'' prior to October 2008.

** The Lucasfilm Ltd. variant also makes a surprise appearance on the 1998 Japanese VHS of ''The Little Mermaid''.

** The last Disney releases with this logo:

*** VHS: The Special Edition release of ''Aladdin'' on October 5, 2004 (however, the logo appears on the packaging and tape of the 2005 Special Edition release of ''Bambi'', but not on the movie itself; unlike the DVD).

*The "DELL PC" version is exclusive to the THX Picture and Sound Optimizer disc.

*The DVD variant was also seen on the Pioneer DVD releases of ''Akira'' and ''Tenchi Muyo In Love'' (The LaserDisc variant also appears on the LaserDisc release of the latter), among other anime titles. It debuted with the first release of the format in the U.S., ''Twister'', on March 24, 1997. Early DVDs from 1997-2000 that were THX-certified play this trailer either as soon as the disc is read or right after the relevant home video logos, but before any menus. While the last US release of this variant was on May 23, 2006 with the uncut DVD release of ''The Boondock Saints'', this variant continued to appear on international releases past this release, namely the Japanese DVD of ''The Uchoten Hotel'' (released on August 11, 2006) as well as the French DVD of ''Underworld: Evolution'' (released on October 11, 2006).

*The remastered version can be seen before every showing of Aerosmith's ''Deuces are Wild'' concert residency.
