There's no doubt that director Alex Gibney's new documentary

film, Going Clear: Scientology and the Prison of Belief, based on the

book of the same name, is a powerful look at what many believe is a polarizing

religion. The film, which first premiered at Sundance and briefly hit theaters

before it debuted on HBO, takes a look at the history of Scientology, its

celebrated celebrity figureheads and what certain members say drove them to leave the organization.

Cruise and John Travolta -- 'They Owe People an Explanation!'

Not surprisingly, the Church doesn't agree with the claims

made in the film, saying -- in a statement released to The Insider -- that it is nothing more

than "bigoted propaganda built on falsehoods invented by admitted liars." In

fact, the group has responded vociferously on its website, Freedom, asserting that "the courts

have debunked the ludicrous 'human trafficking' and 'involuntary servitude'

allegation against the Church that Lawrence Wright promoted in his Going Clear

book and that HBO is exploiting."

We didn't expect the film to answer every question or

allegation about the controversies it covers -- but it still left us with some

unanswered questions.

1. Does the Church maintain secrets about its celebrity

members? At one point, the film

implies that John Travolta is trapped in the Church, held by secrets collected

during auditing sessions. But Gibney doesn't explicitly say what that might be.

BuzzFeed Newsreports that a spokesperson

for the Church said allegations of blackmail are "false and defamatory" and any

assertion that auditing sessions were being leveraged as "deeply offensive."

2. How involved is Travolta these days? The film

only discussed his early days -- and we know what he's been up to lately.

3. How did the Church feel about Tom Cruise's 2005

outburst on Oprah's couch? The film shows how Cruise became the Church's

biggest celebrity asset, reaching over 1 billion people across the world per

the film, to promote its message, but what happened when Cruise had this

couch moment, which reportedly hurt his film career?

4. Why didn't Gibney reach out to Katie Holmes for

comment? Cruise's third wife started studying Scientology soon after she

started dating the actor, but no mention of her was made throughout the entire

film nor was she listed among those the production reached out to in the making of the doc.

5. Did Nicole Kidman know of the wiretap allegations on

her phone when she was married to Cruise? One former Church member -- who's

largely been discreditedby the Church -- claimed they

wiretapped Kidman's phone in order to undermine her relationship with

then-husband, Cruise. (She did not participate in the documentary.)

6. Does anyone remember that Cruise allegedly dated Homeland

actress Nazanin Boniadi? In the documentary, it's purported that the

actress was selected and groomed to be Cruise's next girlfriend. However, their

relationship reportedly lasted three months before the Church allegedly ended it.

Google and Getty Image searches

show no results of them to together, outside of Vanity Fair's expose on Cruise's

relationships. The article also reports that Scientology representatives deny any

sort of search or audition took place.

7. Does the Church focus extra attention on promoting

Travolta and Cruise's memberships? There are a number of stars who are a

part of the Church, including GRAMMY Album of the Year winner Beck and Kirstie

Alley. It seems the public has only focused on the two celebrities.

8. Is Paul Haggis' film The Next Three Days a metaphor for escaping the Church? Watch the trailer and you decide.
