Snow White and the Seven Dwarfs had a major celebration thrown by the Walt Disney Company for its 50th anniversary in 1987, which included a worldwide theatrical reissue on July 17 (at a time when movies rarely had day-and-date international rollouts), an NBC TV special hosted by Dick Van Dyke, and a musical stage show at the Disneyland theme park that was even videotaped and aired on the Disney Channel.
Cars came out during Pixar's 20th anniversary. To commemorate this, the Pixar logo fades into "Celebrating 20 Years" written against a black background, with Luxo Junior's light bulb forming the zero in the 20.
Cars 2 celebrated Pixar's 25th anniversary with a Creator Cameo of Pixar head John Lasseter. (It also introduced an uncelebratory first for Pixarnote It was Pixar's first, and so far only, film to be rated as "Rotten" on Rotten Tomatoes, but that's neither here or there.) The theatrical version of the film similarly began with a Logo Joke featuring Luxo Jr. fading into a "Celebrating 25 Years" message, but the home video release begins with the standard logo.
The Good Dinosaur marks 20 years of Pixar's theatrical films, though it misses the milestone by a few daysnote Dinosaur's release is on November 25, 2015, three days after the anniversary of the release of their first film, Toy Story, on November 22, 1995. In Asia, South America, Norway and the Middle East, Inside Out celebrates this milestone, with trailers for Inside Out released in those countries mentioning this.
Finding Dory was released in the year of Pixar's 30th anniversary.
For individual films, on December 10, 2015 ABC commemorated the 20th anniversary of Toy Story with a retrospective special entitled Toy Story at 20: To Infinity And Beyond, featuring new interviews with the cast and crew. This was followed by a showing of the original Toy Story itself.
In fact, a College Student is planning to create a remake of Toy Story 2 to celebrate Toy Story 2's 20th anniversary.
For the 30th anniversary of the Back to the Future franchise in 2015note Most of these took place during the month of October since October 21st, 2015 was when Part II took place.:
Pepsi released the Pepsi Perfect, designed exactly as it appears in Part II. Only 6500 units were made.
Back to the Future: The Complete Animated Series was released on DVD for the first time, in its entirety and uncut. In addition, a "30th Anniversary Trilogy" Compilation Re-release of the movies was released on DVD and Blu-Ray, along with The Complete Adventures, which includes the previously mentioned DVDs and a replica flux capacitor.
In October 21st, the movies came back to cinemas for one day only.
Microsoft celebrated the occasion by including an interesting Easter Egg in its website, where typing in the words "OUTATIME" would pop up the DeLorean flux capacitor, followed by a video of clouds, wherein a flashing of lights are shown, an indication that something is coming, just like how it was portrayed in the movies. The page that is displayed afterwards shows the phrase "Great Scott! The future is precisely on schedule", a reference to one of Doc Brown's lines; the page also displays many of Microsoft's current hardware—HoloLens (VR), Lumia (smartphone), Band (fitness tracker), Surface (tablet/two-in-one laptop) and Xbox One—showcased side-by side with corresponding technologies from The '80s (as an added bonus, the page can be viewed in 3D, if you have the appropriate glasses).
Telltale Games rereleased the video game for the Xbox 360, Xbox One and PlayStation 4, with improved textures, new dialogue and interviews with various staff involved with the game and the films, including the films' co-writer and producer. Steam also had a 75% discount on the game on October 21st, as part of one of its Daily Deals.
Jetpack Joyride added a brand new mode, which has Barry looking like Marty McFly (Doc Brown and Biff Tanner's looks are unlockable), the set is the 2015 Hill Valley from Part II, the jetpack is the 1985 guitar, and the available vehicles are the Flying Skateboard (which gives you a double jump) and the franchise's iconic DeLorean (which gives you a huge boost when it goes over 88). In this mode, hitting hazards does not immediately kill you, instead, you are timed: powerups scattered on the playing field add 5 seconds to your time, and getting hit removes 10 seconds.
LittleBigPlanet 3 gained a Back to the Future inspired campaign for its first DLC, which has Sackboy following Marty McFly and Doc Brown in a recreation of the first movie. Two costume packs are also available.
Wild Gunman was released on the Virtual Console. This is important when you realize that Marty played this very game in Part II.
Movie studios often get updated Vanity Plates on their anniversaries. Movies released during the first year of the updated logos also contain messages denoting the anniversary. (eg, The Voyage of the Dawn Treader in 2010 begins by panning up from the 20th Century Fox structure to some lights spelling out, "Celebrating 75 Years"note Referring to the 1935 merger of the Fox Film Corporation and Twentieth Century Pictures, not the 1915 founding of the Fox Film Corporation. On that note, the updated Fox logo actually debuted one month before the anniversary year began, without the 75 years message, in front of December 2009's Avatar..)
Universal celebrated its 75th anniversarynote referring to the 1915 re-branding as Universal Pictures Company, Inc., not the 1912 founding of Universal Film Manufacturing Company by opening each movie released in 1990 with the logos that graced their works from 1927-1990, and a then-new logo (though they skipped the version that refers to them as Universal International). Fittingly, this montage first appeared at the beginning of Back to the Future Part III.
Universal released a similar video for their 100th anniversarynote referring to the 1912 founding of Universal Film Manufacturing Company, preceding another new logo with the ones used from 1927-2012 (they did not exclude the Universal International ident this time), but showed this montage online instead of during movies.
Skyfall commemorated the 50th anniversary of the Bond films with a bunch of Mythology Gags (one of which gets some importance in the final battle) and a status quo change for Daniel Craig's Bond. It also considered having a Sean Connerycameo but the director felt that Connery appearing as not Bond felt wrong.
It's very common for superhero films to be released during special anniversaries of the characters they're adapting:
2017 would be comic legend Jack Kirby's 100th birthday and while probably coincidental, five movies feature characters created or co-created by Kirby:
Logan was the first. While Kirby didn't create Wolverine and X-23 was created years after Kirby's death, the film is a spinoff of the X-Men Film Series and Jack Kirby did create the X-Men, and Logan features Professor X.
The second was Guardians of the Galaxy Vol. 2. While Kirby did not (co)-create the team itself, the movie did include Kirby creations Groot and Ego the Living Planet.
Star Trek: First Contact was released during the franchise's 30th anniversary, which was also being celebrated by the two TV series on air at the time(seen below in the TV section). The film sees the Next Generation crew go back in time to stop the Borg from changing history and as a result shows humanity's first contact with the Vulcans, pretty much serving as the major starting point of Trek history.
Star Trek: Nemesis, the final Next Generation movie, was released the same year as TNG's 15th anniversary.
Star Trek Beyond was released in 2016, to celebrate the franchise's 50th anniversary, and there are many homages and meta-commentaries on the special occasion.
Mothra VS Godzilla and Ghidorah, the Three-Headed Monster were the 10th anniversary films. The former was first movie to cross two Toho properties (King Kong vs. Godzilla was the first film to cross Godzilla over with another movie monster, but of course Kong isn't a Toho property), while the latter was the first time Godzilla teamed up with other Kaiju and the first time he was portrayed as defending humanity. As another note, this was also the first film to cross over more than two Toho kaiju; crossing over a total of threedifferentkaijumovies; a record of which wouldn't be broken until 1968's Destroy All Monsters.
King Kong vs. Godzilla was created as Toho's 30th anniversary film, which fortunately coincided with the 30th anniversary of the release of the original King Kong; it was also both monsters' third respective film appearances. Then, for the studio's 60th anniversary, they decided to try and remake it. However, due to copyright issues, they opted for Godzilla's most iconic foe, resulting in Godzilla vs. King Ghidorah.
Godzilla vs. Destoroyah, the 40th anniversary film, ended the Heisei series by having Godzilla fight a monster with origins related to the Oxygen Destroyer that killed him in the original film and then killing Godzilla off again; the film even ended with a brief montage of clips from the first film. The unmade American 1994 Godzilla was originally intended to be the anniversary film.
Godzilla: Final Wars ended the Millennium series on the 50th anniversary by having Godzilla fight and kill almost every other monster he had ever faced.
Godzilla (2014) was released 60 years after the original film (though it's 6 months too early to be an exact anniversary). The months before the movie came out saw a promotional toy fair that featured models of the numerous designs of Godzilla and other monsters over the course of the franchise, along with a limited theatrical run of the original 1954 film. Ironically, it was also released just a month too late to celebrate the 40th anniversary of Mothra VS Godzilla (which was released in April of 1964).
The 65th anniversary was marked with both a new movie, Godzilla: King of the Monsters (2019), and The Criterion Collection Blu-Ray box set Godzilla: The Showa-Era Films, 1954-1975. The latter not only came out in the anniversary month of October but doubled as this trope for Criterion, being Spine #1000!
Warner Bros. did a limited theatrical reissue of Willy Wonka & the Chocolate Factory to mark its 25th anniversary in 1996, and the soundtrack was finally given a CD release. When the film hit 30 in 2001, it received a special edition DVD release (as opposed to the previous Vanilla Edition) that brought back many cast and crew members for its special features, and a making-of book (Pure Imagination). For the 40th anniversary in 2011, they went the full Limited Special Collector's Ultimate Edition route with a Blu-Ray package that included the previous disc's bonus features, the book, and a few other physical extras.
The Disney Channel-produced 2016 reboot of Adventures in Babysitting was the 100th film produced for the channel. As such, in the days leading up to its premiere, every other Disney Channel Original Movie was rebroadcast, including older ones and/or films that were rarely rebroadcast.
The Last Jedi's 2017 release marks the 40th Anniversary of the Star Wars Saga - and given it's a ruby anniversary, the Star Wars logo being red for this film even fits. Its release date would have been nearly 40 years to the day of A New Hope's release in 1977, but due to rewrites it was pushed back to December of that year.
Solo was released on May 25, 2018, the 41st anniversary of A New Hope's 1977 release, in which Harrison Ford first appeared as Han Solo.
For the 50th anniversary of the long running Japanese Tora-san movie series (known as Otoko Wa Tsurai Yo, 男はつらいよ, "It's tough being a man" in the original Japanese), a 50th movie "Tora-san, Welcome Back" is being released in 2019. It's directed by the writer and director of most of the films, Yoji Yamada, and stars a number of actors reprising their roles from the series— including Kiyoshi Atsumi as the main character Tora-san, despite the actor passing away in 1996.
Disney is well known for pulling off grand celebrations for important company milestones:
The company celebrated its golden anniversary om 1973 with their "50 Happy Years" campaign. Highlights from the celebration included a special bumper at the beginning of all their theatrical releases, special episode of The Wonderful World of Disney, a float for the 1973 Tournament of Roses Parade the opening of The Walt Disney Story at Disneyland and Walt Disney World, a stage show at Radio City Music Hall (alongside a reissue of Mary Poppins), a film retrospective at Lincoln Center, a two-disc album of Disney songs, a ceremony and three-day celebration at Disneyland, a special edition of the park's Christmas Fantasy on Parade, the release of the studio's newest animated feature Robin Hood, and a Disney-produced halftime show for the 1974 Orange Bowl.
In 1978, Mickey Mouse's 50th birthday was celebrated with a special bumper at the beginning of the studio's theatrical releases, a 90-minute NBC-TV special, the debut of a revival of The Mickey Mouse Club, a reprint of the 1931 children's book The Adventures of Mickey Mouse, a new parade at the theme parks, and a special weekend matinee of Mickey cartoons playing with a reissue of Davy Crockett, King of the Wild Frontier.
