Michael Jackson's "Captain EO" has temporarily closed at Disneyland — and might be gone for good.

The 3D musical movie starring Jackson, which returned to the Anaheim, Calif. park in 2010 after a long hiatus, has been displaced for a new preview of the upcoming film "Guardians of the Galaxy."

By June 19, the "Captain EO" attraction's sign had been removed, prompting super fan Guy Selga to sadly Tweet: "I'm going to be sick."

Disney has said that "EO" is "expected to return at a later date," though some Disney fan blogs — including DlandLive and Mice Chat — are speculating this could be the end of "EO." The Tokyo Disneyland equivalent of the show recently announced the permanent closure of their "Captain EO Tribute," which will shutter on June 30.

"Captain EO" premiered on Sept. 12, 1986 at Walt Disney World in Orlando, Fla., and less than a week later at Disneyland. The 17-minute movie — where Jackson plays the title role — includes two Jackson songs, "Another Part of Me" and "We Are Here to Change the World."

"Captain EO" eventually opened at Tokyo Disneyland and Disneyland Paris. However, by 1998, all of the "Captain EO" attractions had ended their runs at the assorted Disney Parks throughout the world. The company was moved, however, to return the show to its parks in 2010, starting with Disneyland's version, renamed "Captain EO Tribute."
