Former child star Corey Feldman has been subpoenaed to testify against Michael Jackson in his child molestation trial, ABC News has learned.
With jury selection under way in Jackson's molestation trial, "20/20's" Martin Bashir interviewed actor Corey Feldman, who spoke about his relationship with "The King of Pop" during his youth.
Feldman said, "I started looking at each piece of information, and with that came this sickening realization that there have been many occurrences in my life and in my relationship to Michael that have created a question of doubt."
Jackson, 46, is accused of molesting a now-15-year-old boy who spent time at his Neverland ranch and is believed to be a cancer survivor who appeared in Bashir's 2003 British documentary "Living With Michael Jackson." The pop star has pleaded not guilty to 10 charges that include felony conspiracy with 28 overt acts involving child abduction, false imprisonment and extortion.
Bashir joined ABC News' "20/20" in September 2004.
As a teen, Feldman -- known for his roles in movies such as "Gremlins," "The Goonies" and "Stand by Me" and who appeared in the first season of the celebrity reality show "The Surreal Life" -- became good friends with Jackson. They were often seen together, dressed in similar outfits. Their friendship waned and finally ended in 2001. Feldman later released "Megalo-Man," a highly critical song about Jackson on his CD, "Former Child Star," released in 2002.
However, in an exclusive interview, Feldman, now 33, speaks out with surprising new claims about his relationship with Jackson. Until now, the actor has stood by Jackson, and he tells Bashir why he is now coming forward with allegations about their friendship.
Feldman said speaking out has finally become a responsibility and a duty. "This child -- if he's telling the truth -- and the other children like him -- if they're telling the truth -- they're small voices, they're weak voices," he said.
Feldman said he hopes the allegations against Jackson are proved false, but said he feels compelled to speak out. "So I'm here to say I hope and I pray that these things never happened, and if they never happened, then there's some real sickness with a lot of people. But if they did happen, then there's a lot of sickness with one person. And that person needs to be punished."
Feldman stressed in his interview with Bashir that Jackson never molested him or touched him improperly and that there was no sexual contact between them. But he said he has re-evaluated his friendship with Jackson and has concluded that there were things that happened in their relationship that were inappropriate and wrong.
"If you consider it inappropriate for a man to look at a book of naked pictures with a child that's 13 or 14 years old -- then your answer would be yes."
Feldman says he had such an encounter at Jackson's home when he says they stopped there on the way to Disneyland. "We went to his apartment, and I noticed a book that he had out on his coffee table. The book contained pictures of grown men and women naked. And the book was focused on venereal diseases and the genitalia." Feldman said the singer sat down with him and explained the photos to him.
