The Church of Scientology
is on the attack against the director of a documentary eviscerating the org., claiming the guy who made the most indicting claims is a known liar.
A rep from Scientology tells TMZ ... the man featured in the movie who claims Church officials illegally wiretapped Nicole Kidman
cannot be believed because he has admitted under oath in a court case he's lied about the Church before.
The rep says in December Marty Rathbun
-- a former Scientology exec featured in the documentary -- was under oath in a deposition
late last year and admitted he lied about Scientology practices. He also admitted to obstruction of justice.
We've confirmed Rathbun did indeed lie, but his position -- which he discussed in the deposition -- is that he lied to protect the Church and cover up its misdeeds. Rathbun says he was an executive in the Church at the time and did not want to squeal on alleged misdeeds of Church leaders.
Rathbun claims in the documentary that he was tasked with facilitating the breakup of Tom Cruise
and Nicole Kidman, because her dad was a psychologist and the Church felt he was influencing the actor into distancing himself from Scientology.
The Scientology rep expressed frustration at the flick, saying, "These people personify the famous quote by Winston Churchill, 'A lie gets halfway around the world before the truth has a chance to put its pants on.'"
