Amblin Entertainment

Background
Amblin Entertainment is a production company founded by Steven Spielberg (the director of said short film), Kathleen Kennedy, and Frank Marshall in 1981. Named after a short film titled Amblin '  (1968), its logo features the silhouette of the titular character E.T. riding in the basket of Elliott's bicycle flying in front of the moon, from E.T. the Extra-Terrestrial, in which they are the company's official mascots.

1st Logo (June 8, 1984-)
Logo: A print version of the Amblin logo in white, with an inverse silhouette of Elliott and E.T. flying in front of the moon (represented by an outline) and "AMBLIN" to the right in a font known as Optima.

Variants:
 * On Gremlins, the logo appears in the color scheme used from the standard version of the logo, but with the "moon" colored ; "AN" is above the logo, and "PRESENTATION" is below it.
 * Starting with Jurassic World in 2015, the silhouette of Elliott and E.T. have been updated to match the current onscreen logo, with the cape being redrawn and more accurate. It looks less like a chicken riding a bicycle.

Technique: None.

Music/Sounds: The ending music from any given soundtrack.

Availability: Current and common. The in-credit Amblin logo debuted on Gremlins, and can also be seen on Fandango, all four Men in Black films, and The Mask of Zorro.

2nd Logo (June 7, 1985-August 8, 2014, September 21, 2018, December 10, 2021)
Logo: We see a close-up of the moon, which zooms backward until it is on the left side of the screen. Right before the moon stops in its place, the silhouette of a young boy on a bicycle with an alien in its basket (Elliott and E.T. from E.T. the Extra-Terrestrial) slowly flies in front of the moon from the left side of the moon's border, stopping in the middle (even when the bicycle stops, the wheels continue to move). At the same time, two / stripes move in from both sides of the screen. The stripe that comes in from the bottom left side places itself right underneath the moon, while the stripe that comes in from the top right side places itself near the top of the moon (this creates a small space to the right of the moon bordered by the stripes on the top and the bottom). When the moon and stripes are in place, the word "AMBLIN" (once again, in Optima) appears in a strange fade-in (shadows form the letters one at a time, referred to as a "shadow wipe"/"refracting prism"). When the word "AMBLIN" is finally revealed, the wheels begin to stop and smaller text appears under the bottom / lines that reads "ENTERTAINMENT" in spaced out letters to fit the width of the bottom line. Both words are in a similar thin font.

Moon Colors:
 * Earlier films, The House With a Clock in its Walls: Blue
 * Later films: Realistic white.

Variants:
 * A shorter version shows the moon and stripes in place without animation, and it just shows the fade in of the company name, as well as the wheels turning. This version first appeared on Who Framed Roger Rabbit, and made its last appearance on Catch Me If You Can.
 * On some movies such as The Goonies (1985) (first film to use the logo), Joe Versus the Volcano (1990), Cape Fear and Hook (both 1991), and A Far Off Place (1993), shot and released in 2.35:1 (anamorphic Panavision) as well as early ITV airings of both Back to the Future Part III (1990) and The Flintstones (1994), the moon is flipped backwards. Full screen versions of some of these movies (e.g. 2001 VHS release of The Goonies) use the normal variant on certain prints.
 * A still version appears at the end of War Horse, Lincoln, and The Hundred-Foot Journey (the final movie to use this logo; with the closing theme), West Side Story (2021), as well as some TV shows from Amblin.
 * A black & white version of the logo appears at the end of Hereafter.
 * A medium-length version is known to exist on the original trailer of We're Back!: A Dinosaur's Story, with the logo starting in the middle of its formation and also having the entire name fade in at once.
 * On Dad, the logo fades in after the credits roll.
 * On 4:3 full screen prints of later films from 2005 until 2014, starting with The Legend of Zorro, the logo zooms out to a much farther distance than usual. This is because the letters were shot and released in 2.35:1 (anamorphic Panavision) and framed for 2.39:1 scope.
 * On the ending of Memoirs of a Geisha, it starts with the stripes positioning.

Technique: All traditional animation.

Music/Sounds: A light orchestral theme composed by John Williams was used with this logo on Young Sherlock Holmes, The Color Purple, The Money Pit, and the 1987 theatrical reissue (as well as the 1988 VHS and the 2012/2017 Blu-Ray/DVD releases) of E.T. the Extra-Terrestrial. However, it is usually silent, or has the film's closing score.

Availability: Common.
 * The flipped moon variant debuted at the end of The Goonies, while the normal variant debuted at the end of Back to the Future, and can be found on every Amblin film from this era (except Schindler's List, The Bridges of Madison County, Minority Report, Flags of Our Fathers, and Letters from Iwo Jima, as well as the three Amblimation productions, which featured that company's special logo, and the aforementioned with the 1st/print logo on the credits).
 * Most prints of E.T. the Extra-Terrestrial don't show this logo despite showing the logo on the packaging, except on the 1988 home video release and ABC Family/Freeform's print of the film.
 * The last film to use this logo was The Hundred-Foot Journey.
 * Despite being retired after the aformentioned film, this logo made a surprise appearance on The House with a Clock in Its Walls, fitting with the retro theme, and West Side Story (2021, albeit still).
 * This appears at the end of the TV movie Amazing Stories: The Movie II.

Legacy: The way Elliot's cape is positioned makes him look sort of like a chicken riding a bicycle.

3rd Logo (June 12, 2015-)
Logo: Same concept as before, only CG is used, and the moon and silhouette are three-dimensional. The moon swooshes down and hovers to the left of the screen, while Elliot and E.T. fly on the screen from behind, making an immediate right in front of the moon and parking to form the graphic. Also, the word "AMBLIN" no longer has the strange shadow wipe effect, and instead uses a more gradual fade-in from the left, and the rest of the logo (the and  bars and "ENTERTAINMENT", which, along with "AMBLIN", now have texture on the logo) fades in. The finishing background is now -gradient black (evening sky). If you look closely, you can see E.T.'s finger glowing.

Variants:
 * On Jurassic World: Camp Cretaceous, there is a custom variation, where it picks off where the Universal Pictures/DreamWorks Animation Television logo combo left off; we pan to the left of the DreamWorks logo-shaped continent to reveal an Amblin logo-shaped archipelago, where the camera then zooms underneath Elliot's cape to start the show.
 * On The Fablemans, the logo's animation starts over the Universal Pictures logo, but it fades to its background when the logo is nearly done forming.

Technique: A recreation of the previous logo in CGI.

Music/Sounds: The ending of the orchestral theme from the previous logo, the opening theme of the movie or silence.

Music/Sounds Variant: On The Fablemans, the tail end of the 2012 Universal Pictures fanfare, originally composed by Jerry Goldsmith and arranged by Brian Tyler, is played over the logo.

Availability: Current. Debuted on Jurassic World and has appeared on all Amblin films since (except for The House with a Clock in Its Walls and West Side Story (2021), both which used the previous logo). The version with the theme debuted on The BFG.
