Tom Cruise's Mission Impossible: Ex-Scientology Executive Reveals How Church Tried To Convert His Former Lover Penelope Cruz

The man who helped the Church of Scientology create its' iron grip on Tom Cruise has detailed how Cruise's Vanilla Sky co-star, and ex-girlfriend, Penelope Cruz was audited by Scientology during the pair's three-year relationship.

Mark "Marty" Rathbun, who was Inspector General of the Church, spoke out in a new documentary that aired in Britain on Monday night titled Scientologists at War, detailing how Church leader David Miscavige had him personally work on a hush-hush project in the '90s -- to help the Hollywood mega-star.

The former high-ranking church member revealed how the controversial religious organization showered its' poster child Cruise with their services and staff to help him overcome his divorce from Nicole Kidman, and subsequent introduction to Cruz.

"Cruise started making some noises about getting some help from the Church of Scientology, and Miscavige had me drop me everything," Rathbun told the Channel 4 expose, which provided a rare insider view of the controversial religion from those who have renounced their membership.

Everything was designed to obligate Cruise to the Church and its' head honcho Miscavige, who would later be the actor's best man at his wedding to Katie Holmes.

"Once Miscaviage was able to hobnob with Cruise again, he was done with me," Rathbun said.

"He Miscaviage actually tried to denigrate me a little bit in Tom's eyes. I was his biggest opinion leader having salvaged his marriage, his kids, his family life -- even his career. It was crazy. Miscavige had to try and undermine me in front of Cruise."

Cruise and Cruz, once consider Hollywood's most influential power couple, split in 2004 after three years together. He later remarried while the Spanish actress, 39, is now pregnant for a second time and married to Javier Bardem.

In an eyebrow-raising 2012 Vanity Fair expose, investigative journalist Maureen Orth reported that the reason for the Cruise-Cruz split was because the Oscar-winning actress would not give up her Buddhist beliefs and adapt to the Church of Scientology.

Miscavige, Orth reported, referred to Cruz as "dilettante" when he discovered she wouldn't quit her religion.

According to the Church, Rathbun is "an anti-Scientologist, desperate and delusional."

It was said he was "expelled from the Church for violating Scripture" and has "a history of malfeasance."

But his claims about Cruise's leading a life in a gilded cage are consistent with other ex-Scientologists.

Amy Scobee, a former high-ranking Church executive who fulfilled various management positions -- including at the Celebrity Centre sector -- during 27 years in the Church, previously detailed how she and other influential staffers were assembled to establish Cruise's seven-bedroom, nine-bathroom $35 million home with Kidman and their children, Isabella and Connor, in Pacific Palisades, Calif.

It was finished with the best staff Scientology dollars could engage, she said.

"It was a confidential project that I was not allowed to discuss with any other staff member... it was being run directly by Miscavige and his wife," Scobee -- who "blew" the organization (Scientology speak for an unauthorized departure) in 2005 -- previously told this author.

"To that effect, it was a privilege: an honor to set him and Nicole up. But the clear goal was to ensure that he was set up with Scientologists only around him. Now that I am out of the Church, I have discovered that it is against the law, because the Church was using members to give him special favors. Members working for him, directly. Putting together his sound theater, cooking, various work."
