THX: Difference between revisions

'''Nicknames''': "Wings", "It Begins", "Blue THX"

'''Trailer''': We start with a black screen before the following white text fades in: "'''For the past 35 years, motion picture loudspeaker systems have not changed...'''" Later it fades out, and another white text appears reading "'''Lucasfilm Ltd. and this theatre are pleased to introduce a new motion picture sound system.'''" That text fades out, and after a few seconds, the letters "THX", underlined and which have the slightly taller "T" stem extend over the other two letters, appear in a glassy {{color|lightskyblue|sky-blue}} color. The color fades in majestically with "LUCASFILM LTD." above it and "SOUND SYSTEM" below it, both in small text. It stays on screen for about 10 seconds, then slowly fades out with the text above and below the logo.

'''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''.

'''Variant''': The logo was slightly enhanced for THX's 10th anniversary, with the text being changed to {{color|gray}}.

'''FX/SFX''': The text and THX logo fading-in and out.

'''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.

'''Availability''': Extremely rare. This was only used on the theatrical premiere of ''Star Wars: Episode VI - Return of the Jedi'' in theaters located in Dallas and Hollywood, and was never used on THX-certified video releases. That said, it can be seen on select Demo DVDs and at THX's official website (plus their official Vimeo and YouTube).

'''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.
