As one of Hollywood's most powerful stars, Tom Cruise is accustomed to being in control.
But when his wife of five years, actress Katie Holmes, filed for divorce in New York on June 29, the actor, who has been filming the sci-fi thriller Oblivion in Iceland, was caught completely off guard.
"He had no idea this was coming," a source tells PEOPLE in this week's cover story. "He's totally devastated and heartbroken."
In reportedly moving for sole custody of their 6-year-old daughter Suri, Holmes has signaled she will not be backing down.
The actress did have some important help in her corner: A source tells PEOPLE that her Toledo, Ohio-based lawyer father, Martin, came to New York to aid in quickly orchestrating her decisive exit.
But the final decision was all hers. "She's a strong person and makes up her own mind," says a source in her circle. And in the choice to end her marriage, "She's unwavering."
For much more on the split, including Holmes's dramatic exit from the marriage and the legal battle ahead, pick up this week's issue of PEOPLE, on newsstands starting today.
Tom Cruise has hired famed divorce lawyer Dennis Wasser to represent him in his split from Katie Holmes.
He's the same attorney he used in his bitter divorce from Nicole Kidman a decade ago.
As Tom Cruise' and Katie Holmes gear up for what could be one of Hollywood’s nastiest custody battles, one thing they will definitely be fighting over is Tom's dedication to raising their daughter as a Scientologist, RadarOnline.com is exclusively reporting.
As we previously reported, the couple announced their shocking split Friday after five years of marriage with Holmes filing for divorce in New York City and requesting sole custody of six-year-old Suri.
"Katie does not want Suri raised as a Scientologist or raised under the tenets of the church," a source close to the actress tells RadarOnline.com. "She wants her to enjoy a 'normal' upbringing with a wide variety of friends and a good schooling. She believes that will not happen if she is raised as a Scientologist; it's one of the major things she and Tom fought over when they were together. Now they are apart she is adamant she is going to have Suri raised outside of the church.
"Katie even enrolled Suri in a Catholic pre-school a few years back, which Tom grudgingly agreed to after a lot of fights, but not as a long term measure. He wants Suri raised and schooled as a Scientologist and wants her friends to be fellow Scientologists."
A source close to Cruise tells RadarOnline.com that Katie could be gearing up for the fight of her life as Tom will NEVER allow Katie to take his daughter away from Scientology.
"Tom is incredibly passionate about Scientology, this isn't just some hobby for him and he doesn't just act as a spokesperson," the source says. "He truly believes in the church and its teachings and truly believes that it is imperative that his children are raised as Scientologists. Tom believes Scientology changes people's lives for the better and, obviously, he wants what is best for his children.
"Tom will move Heaven and Earth to ensure Suri stays a Scientologist, at least until she is of an age to make a decision to leave on her own accord. But until then, make no bones about it, Suri will be raised within the church."
Katie Holmes family has been getting information for years on "the iron grip" that Scientology has on Tom Cruise's personal and business life, Marty Rathbun tells RadarOnline.com in a blockbuster exclusive.
Rathbun is a high profile ex-Scientology member and he tells Radar it is a personal friend who has been the conduit of information to Katie's family.
"I did audit sessions with Tom Cruise from 2001-2004, and I can tell you that I have a friend that has been providing Katie Holmes' family information for years about the iron grip the Church of Scientology has on Tom Cruise's family and professional life. This has been going on for at least four years" Rathbun says.
Rathbun declined to reveal if the information was being given to Katie's lawyer father, Martin, or her mother Kathleen.
Marty Rathbun became a Scientologist in 1977 and quickly rose to the highest ranks within the church and became a Sea Org, which troubleshoots and audits people and problems, within the organization.
According to literature, "Auditing is a central practice in Scientology through which a practitioner is cleared of negative influences known as engrams in order to heighten spiritual awareness and access currently untapped potential. Auditing sessions involve two people: the person being audited and an auditor. The person being audited is generally referred to as a pre-Clear in public Scientology literature, although Clears continue to participate in a similar process. The auditor monitors a device known as an electro-psychometer, or E-meter. The pre-Clear holds a metal cylinder in each hand, both of which are attached by wires to the E-meter."
"Katie's father is very involved in the divorce proceedings and working closely with Katie's lawyer. Katie's father has truly been her rock in the last several months and she just doesn't know where she would be without him," a source close to the situation tells RadarOnline.com.
Rathbun left the church in 2004 because of alleged violence he witnessed at the headquarters in Florida. Marty's book, What Is Wrong With Scientology? was recently released and is available on Amazon for $17.76.
The final straw in Katie Holmes' decision to file for divorce was that she was convinced Tom Cruise was going to send 6-year-old Suri away to a hardcore Scientology organization known as Sea Organization ... sources connected with Katie tell TMZ.
Sea Org, as it is known, is where the highest levels of Scientology are taught and kids as young as five can be sent to live there ... without their parents -- and our sources say Tom is a big fan.
Our sources say Katie and Tom had been arguing over Suri's indoctrination into Scientology -- and we're told the Sea Org was the flashpoint.
The Sea Org has been often compared to a boot camp and several ex-Scientologists (including Oscar winner Paul Haggis) have been outspoken against its military-like conditions. The Freewinds, the massive Scientology boat that was the location of Cruise's infamous birthday party in 2004, is entirely staffed by Sea Org members.
According to the official Scientology website, members of Sea Org sign "a one-billion-year pledge to symbolize their eternal commitment to the religion and it is still signed by all members today."
Katie herself has first-hand knowledge of the Sea Org. When Holmes and Cruise first hooked up in 2005, Jessica Feshbach, a prominent Scientologist who had been with the Sea Org since 1994, was transferred and became Katie's assistant/Scientology chaperone. Feshbach, in one of Katie's first interviews after getting together with Cruise, was described by a writer for W magazine as "cold-eyed" and "a third-wheel."
In the end ... we're told Katie felt the only way to save Suri from being shipped off to Sea Org was to file for divorce and seek sole legal custody.
Katie Holmes' Hollywood fairy tale with Tom Cruise definitely did not have a happy ending.
When the 33-year-old actress filed for divorce from Cruise, 49, last Thursday -- aggressively moving for sole legal custody of daughter Suri, 6 -- it was the culmination of a year-long attempt to break free of a confining, Scientology-influenced marriage to Cruise, sources tell the new Us Weekly, out now.
"Every move she made and everything she did was controlled . . . She felt like she was in Rosemary's Baby," says one insider, referring to the classic 1968 horror film, in which an aspiring young actress (Mia Farrow) unwittingly bears a child for her husband's Satanic cult.
Indeed, her shocking divorce filing, which has blindsided a "furious" Cruise, wasn't simply about the Kennedys star's own personal contentment, a Holmes source says.
"This is about protecting her daughter," the insider explains to Us. "She wants to be in charge of how Suri is being raised and didn't want her to have an exclusively Scientology education."
The first source puts it more bluntly: "She felt she had to get out to save her daughter."
