Who is Tom Cruise from Inside Scientology: The Story of America's Most Secretive Religion and what is their importance?

Tom Cruise is one of Scientology's biggest names. A loud proponent of Scientology, Cruise has a long history with the church and with David Miscavige, as the two are dear friends. Miscavige reportedly has spent millions of dollars over the years keeping Cruise happy, as his participation in Scientology alone has generated membership. However, critics point out that Cruise's overwhelming passion for the church at times seems odd, and actually gives Scientology a bad image. Although Cruise has had issue with the church, at times, he is still the most visible supporter, even helping the organization implement their study technologies and detox programs nation wide.
