Here post info on attractions that no longer exist in the park. Here is some about Captain EO.
In 1986, a new 3-D movie appeared in both Disneyland in California and Epcot in Florida named Captain EO. Wikipedia recaps the story as -
"...the story of Captain EO and the ragtag crew of his spaceship on a mission to deliver a gift to a wicked alien queen, the Supreme Leader, on her home world of rotting, twisted metal and steaming vents. Captain EO's alien crew consists of his small flying sidekick Fuzzbucket, the double-headed navigator and pilot Idee and Odee, robotic security officer Major Domo, a small robot Minor Domo (who fits like a module into Major Domo), and the clumsy elephant-like shipmate Hooter (Tony Cox) who always manages to blunder the crew's missions. Upon arriving on the planet, the crew is captured and sentenced to be tortured.
Before being sent away, EO tells the Queen that he sees the beauty hidden within her, and that he brings her the key to unlock it: his song. The two robot members of the crew transform into music instruments and the crew members begin to play the various instruments. As Hooter runs toward his instrument, he trips over EO's cape and breaks his instrument, stopping the music.
The spell broken, the Queen orders her guards to capture Captain EO and his crew. Hooter manages to repair his instrument and sends out a blast of music, providing EO with the power to throw off the guards. He uses his power to transform the dark hulking guards into agile dancers who fall into step behind him for a dance number. As EO presses forward toward the Supreme Leader she unleashes her Whip Warriors, two cybernetic defenders each with a whip and shield that can deflect EO's power.
The others all run away leaving Captain EO to fight the whip warriors alone. EO is trapped by a closing gate and is preparing for a last stand as both the whip warriors draw their whips back for a final blow. Fuzzball drops his instrument and speedily flies over to tie the two whips together, causing the whip warriors to be thrown off balance giving EO an opportunity to transform them as well.
With no further obstacles, EO uses his power to transform the Queen into a beautiful woman, her lair into a peaceful Greek temple and the planet into a verdant paradise. A celebration breaks out as EO and his crew triumphantly exit and fly off into space."
The attraction was succesful and was built in Tokyo Disneyland in 87, and then "EuroDisney" as it was called, known today as Disneyland Paris, in 1992. Michael Jackson played Captain EO, and the film was produced by none other than George Lucas. The ride is now just a part of Disney past with the attraction closing in Epcot in 1994, TDL in 1996, DLR in 1997, and finally in Disneyland Paris in 1998.
I am a big Star Wars Disney Geek, and would love to meet some more.
