Trapped In The Closet came out in 2005 so the internet wasn’t as vast in information yet or as available. Not even most Scientologists knew the truths of their teachings. So how did Matt and Trey get such in-depth info on the subject?
It was well known at the time. There were anti-Scientology websites like Operation Clambake and the Lisa McPherson Trust and XenuTV that had a lot of info. There were lots of legal documents IIRC. The Church of Scientology always publicly denied the Xenu story but IIRC they had had to admit it under oath in some trial that it was an authentic teaching.
They definitely did not learn it from Isaac Hayes. I don’t know what OT level he was on but if he was OT3 (where they learn the Xenu story) or higher he would definitely not tell anybody about it. That would be a major ethics violation. LRH even said people could get so shocked hearing about it they could get sick or even die of they learned about it before reaching OT3.
And that’s the thing about the Xenu story. All scientologists will deny it. Most probably because they genuinely don’t know about it, and those who do know about it will deny it because they have to.
The Xenu story has been floating around forever. It’s not a huge secret. Although Scientology protects it fiercely because it’s their most sacred “truth” and deep down I think even some of them know how absurd it is if they were to make this public. Plus since it’s the highest OT level you can get to currently, if they just released the info you learn at that level now, Scientologists have no reason to pay for it later.
The reason many stay in Scientology after learning the Xenu nonsense is as Leah Remini described - by that time you’ve invested years of your life and tens of thousands of dollars or more for you to get the “truth” of the universe as brainwashed aliens souls in DC-8’s and a galactic warlord. You think “there HAS to be more than this” so you stay in it because you don’t want the shame of believing you wasted all that time and money.
Also check out the Wikipedia page: The Xenu story first leaked in the 1970s , was part of a Court case in the 80s, was shown as a cartoon on BBC:s Panorama in 1987 and it was posted on the Internet in 1994. (Believe it or not, Internet existed way before 2005)

Being in Hollywood they knew the people who were involved with that.
