While security was heightened surrounding Sundance screenings of the explosive Michael Jackson doc “Leaving Neverland,” festival attendees noticed that Corey Feldman is also at the fest being tailed by a bodyguard.

But it turns out Feldman is in Park City, Utah, separately shopping a doc of his own that details shocking sexual abuse in Hollywood. (As a young star, Feldman was close friends with Jackson, but he wrote in his 2013 memoir, “Coreyography,” that the singer never acted inappropriately toward him.)

Feldman’s rep explained to Page Six that the “Goonies” star is at Sundance to meet with distributors for his own documentary, in which he reportedly investigates a Hollywood pedophile ring that preyed on young actors — including himself.

He’s said that he feared for his safety while making the doc, which was financed through Indiegogo.

Last year, Feldman claimed an attacker tried to stab him, reports said.

His rep told us, “There were the two attempts on his life and many threats, so he has had security since launching his campaign.”

Jackson’s estate has slammed “Leaving Neverland” as “character assassination.”
