Appearance, tabloids, Bad, autobiography and films (1986–87) {7}

Jackson's skin had been a medium-brown color for the entire duration of his youth, but starting in the mid 1980s, it gradually grew paler. The change gained widespread media coverage, including rumors that he was bleaching his skin. According to J. Randy Taraborrelli's biography, in 1986, Jackson was diagnosed with vitiligo and lupus; the vitiligo partially lightened his skin, and the lupus was in remission; both illnesses made him sensitive to sunlight. (His long-term dermatologist Dr. Arnold Klein confirmed this on Larry King Live, after his death.) The treatments he used for his condition further lightened his skin tone, and, with the application of pancake makeup to even out blotches, he could appear very pale. The structure of his face had also changed: several surgeons speculated that he had undergone multiple nasal surgeries, a forehead lift, thinned lips, and cheekbone surgery.

Jackson lost weight in the early 1980s because of a change in diet and a desire for "a dancer's body". Witnesses reported that he was often dizzy and speculated that he was suffering from anorexia nervosa; periods of weight loss would become a recurring problem later in life.Some medical professionals have further speculated that he was suffering from body dysmorphic disorder, a psychological condition whereby the sufferer dislikes his appearance and has no concept of how he is viewed by others.Jackson claimed that he had only two rhinoplasties and no other surgery on his face, although at one point he mentioned having a dimple created in his chin.

He became the subject of increasingly sensational reports. In 1986, the tabloids ran a story claiming that Jackson slept in a hyperbaric oxygen chamber to slow the aging process; he was pictured lying down in a glass box. Although the claim was untrue, Jackson had disseminated the fabricated story himself. When Jackson bought a chimpanzee called Bubbles from a laboratory, it was reported as an example of increasing detachment from reality. It was reported that Jackson had offered to buy the bones of Joseph Merrick (the "elephant man") and although untrue, Jackson did not deny the story.Although initially he saw these stories as publicity, he stopped leaking untruths to the press as they became more sensational, so the media began making up their own stories.

These reports became embedded in the public consciousness, inspiring the nickname "Wacko Jacko," which Jackson came to despise. Responding to the gossip, Jackson remarked to a reporter:

Why not just tell people I'm an alien from Mars. Tell them I eat live chickens and do a voodoo dance at midnight. They'll believe anything you say, because you're a reporter. But if I, Michael Jackson, were to say, "I'm an alien from Mars and I eat live chickens and do a voodoo dance at midnight," people would say, "Oh, man, that Michael Jackson is nuts. He's cracked up. You can't believe a damn word that comes out of his mouth.

Jackson starred in the 3-D film Captain EO, directed by Francis Ford Coppola. It was the most expensive film produced on a per-minute basis at the time, and was later hosted in Disney theme parks. Disneyland featured the film in its Tomorrowland area for nearly 11 years, while Walt Disney World screened the film in its EPCOT theme park from 1986 to 1994. With the industry expecting another major hit, Jackson's first album in five years, Bad (1987), was highly anticipated. It had lower sales than Thriller, but was still a substantial commercial success, spawning seven hit singles in the U.S., five of which ("I Just Can't Stop Loving You", "Bad", "The Way You Make Me Feel", "Man in the Mirror" and "Dirty Diana") reached number one on the Billboard Hot 100 charts, more than any other album. As of 2008, the album had sold 30 million copies worldwide.
In 1987, Jackson disassociated himself from the Jehovah's Witnesses, in response to their disapproval of the Thriller video. The Bad World Tour began on September 12 that year, finishing on January 14, 1989. In Japan alone, the tour had 14 sellouts and drew 570,000 people, nearly tripling the previous record of 200,000 in a single tour. He broke a Guinness World Record when 504,000 people attended seven sold-out shows at Wembley Stadium. He performed a total of 123 concerts to an audience of 4.4 million people, and gained a further Guinness World Record when the tour grossed him $125 million. During the trip he invited underprivileged children to watch for free, and gave donations to hospitals, orphanages, and other charities.
