Fresh off the release of his documentary Demon House, we’ve just learned that “Ghost Adventures” star Zak Bagans is executive producing Manson’s Bloodline, an upcoming documentary on the finally-dead Charles Manson.

Bagans tells TMZ that filming began on the doc shortly before Manson’s death last year; “it will cover everything from Manson’s life to the news of his death and the court battle over his body… to exclusive footage of his open casket funeral,” he tells the site.

The doc will also focus on Manson’s grandson and his quest to meet the infamous cult leader face to face… a meeting that never happened when Manson was alive.

“We’re told a few networks are in talks with Zak about picking it up,” TMZ notes.
