The Alex Gibney-directed documentary premiered at Sundance in January.

The trailer for Alex Gibney's Scientology documentary has debuted online. 

In the one-minute clip, a chorus of voices are heard describing their experiences with Scientology. "There is no logical explanation other than faith," a voice finally concludes. 

The film, which had its premiere at Sundance in January, is based on the book Going Clear: Scientology, Hollywood and the Prison of Belief, by New Yorker writer Lawrence Wright

It's set to premiere on HBO on March 29.

In a Sundance festival review, The Hollywood Reporter's film critic Leslie Felperin deemed the title "a rigorous, impassioned and timely exposé of Scientology."
