Bambi (1942) was Scenery Porn, with a little bit of story thrown in.
A surprising example is provided by obscure war-time Disney movies Saludos Amigos (1943) and The Three Caballeros (1944). Both have some truly amazing background art, mainly thanks to the artistic influence of designer Mary Blair.
Sleeping Beauty (1959). Not only are the backgrounds meticulously and beautifully painted, the animation is flawless and the foregrounds are no less breathtaking. There's a reason this movie almost bankrupted Disney.
The little-remembered The Rescuers Down Under (1990) had some amazing shots of the Australian Outback, and the New York scenes were pretty stunning as well.
The ballroom scene in Disney's Beauty and the Beast (1991) is a brief bit of Scenery Porn. The background was done digitally, while the characters dancing were hand-drawn. As a rule, when the camera flies backwards in a widening spiral with a rotating viewpoint through a massive and detailed candelabra while the room is spinning in one direction and the dancers spin in the opposite direction and there are no mistakes, you know two things: 1) this was done with computer graphics, and 2) this is goin' on the ol' résumé. Disney still uses this clip to blow the socks off of viewers.
Aladdin (1992) is full of Scenery Porn, drawn from reference photos of actual Islamic architecture (almost all of it 16th- and 17th-century Iranian, as that's where the photos were taken.)
The Lion King (1994) in its gorgeous shots of African plains and jungles.
Pocahontas (1995) - literally painting with all the colors of the wind.
Treasure Planet (2002) begins with a shot of a spaceport shaped like a crescent moon, displaying every building and ship, and when zoomed in enough, the inhabitants. The visuals build up from there.
The Princess and the Frog was intended to show off exactly what hand-drawn animation was capable of, and it shows. Lush colors everywhere, and the various color schemes (gold, purple and green) have a large role in the movie.
Winnie-the-Pooh tends to be overlooked, but it truly marvels in showing off the Hundred Acre Wood, 2011 style. Underwater scenes especially stand out.
Wreck-It Ralph. Sugar Rush qualifies due to the sheer amount of detail and lushness to the candy. Basically, imagine a world holding all the tracks of Mario Kart, animated in CGI and themed to look like candy.
Disney's Frozen rightfully earns its place here, thanks to its beautifully animated ice and snow sequences. Several programs were developed by Disney here to ensure realism in capturing movement of characters in the snow. They even made a program just to make sure that each individual snowflake was unique!
Every production released by Hayao Miyazaki (and Studio Ghibli by extension) manages to pull at least a long sequence of very pretty scenery. (Given Miyazaki's love of flying, it's no surprise that every work has at least one extended aerial sequence.)
Most of Makoto Shinkai's work. Shinkai, in fact, will focus the camera on the Scenery Porn in the middle of important scenes with his characters. 5 Centimeters per Second is the epitome of cloud Porn.
The animated film Patlabor 2 has a large amount of Scenery Porn. The apex of this is the "boat scene" in which two characters have a long, extremely philosophical conversation while riding a small boat down a waterway. As the conversation goes on, the camera view focuses on old buildings, factories, and other features of a near-future Tokyo.
Much of The Sky Crawlers is devoted to featuring the beautiful vistas of Ireland and Poland, as well as the incredibly detailed indoor settings.
Angel's Egg is Yoshitaka Amano's and Mamoru Oshii's visual poem. With only about five minutes of dialog in its seventy minute run time the absolutely gorgeous visuals carry the film's elegant, surreal and poignant "narrative".
Coraline is this trope mixed with plot. The garden and mouse circus scenes in the other world are beyond breathtaking, especially in 3D. All done in stop-motion.
The "Plagues" sequence in The Prince of Egypt is the wrath of God made manifest. It looks awesome. Most of the movie falls into this category, honestly. From simple dialogue scenes showing the vast majesty of the Egyptian empire, to Moses walking out his front- er, tent flap to be greeted with sweeping mountain landscapes, to the crossing of the Red Sea, the movie is pretty much a scenery porn extravaganza.
Kung Fu Panda. Even if you don't count the opening two minute dream sequence storyboarded and overseen by the respected and famous James Baxter (whom you may have been introduced to via The Lion King), just about every shot of the Valley of Peace counts as this... and the Jade Palace... and Chorh-Gom in the Mongolian mountains... and the suspension bridge where Tai Lung fought the Furious Five. Talk about luscious!
Gongmen City in the sequel takes it even further. Just look at all those buildings.
All over the place in Rise of the Guardians. Highlights include each of the guardians' main base of operations - the first walkthrough of North's workshop, the flight to Tooth's palace, various shots of Bunny's warren and even the first visit to Pitch's lair.
Once The Croods set out on their road trip, practically every stop is great to look at, especially the hidden oasis in the rock labyrinth.
Every animated film by René Laloux, director of obscure French weirdness like Fantastic Planet, Gandahar, and Time Masters. Bizarre but beautiful alien worlds that look straight out of a Salvador Dali painting. Fantastic Planet is a particularly bizarre example; wallowing in strange crystalline structures and surreal images. It's Scenery Porn on drugs.
The Little Nemo: Adventures in Slumberland animated movie perfectly captures the jaw-droppingly virtuoso style of artwork that made Winsor McCay's original comic strip so memorable. Even the movie's infamously scary scenes are rendered lushly, with a large amount of fine detail.
The Irish/Belgian/French film The Secret of Kells. It toys with perspective masterfully in some scenes, and others are simply jaw-dropping.
Rio is FULL of this. There are gorgeous scenes of the jungle, but then you get to the flight scenes where we see them overhead, and oh boy! The parade also looks amazing, with dancers in great costumes and beautiful floats. A float featuring a scarlet macaw stands out in particular.
The Rankin & Bass adaptation of The Hobbit does a fine job of this in its scenic shots, as is only proper for an adaptation of Tolkien's work.
TheDragon Hunters movie is this :world in the sky and loads and loads of ancient ruins flying apart. this troper thinks this is the greatest animation sceneries ever.
The Thief and the Cobbler's Recobbled Cut. The whole thing's on Youtube. To use another troper's example, Imagine Aladdin on marijuana and cough syrup. It was made BEFORE CGI was invented.
Sonic OVA had dozens of different environments, combined with some of the best background detail for a 90s Anime.
