It is one of the world’s most secretive and controversial cults… brought to light by one of Hollywood's biggest stars, Tom Cruise. Since its creation in 1953, Scientology has won millions of disciples, up to 40,000 in France alone, according to its leaders. Scientologists follow the teachings of a former bestselling Science Fiction author, L. Ron Hubbard. They believe in reincarnation and undergo extraordinary practices to gain enlightenment. Scientology is also an institution plagued by headline-grabbing scandals when former members go public about their experiences with the sect. While it is recognized as a religion in some countries, others consider it a dangerous cult.
