Lord Of The Rings: Nazanin Boniadi Believes In Scientology Religion
Nazanin Boniadi was a dedicated Scientologist in the mid-2000s, and her mom had also been a Scientologist.
It's a set of beliefs and practices and an associated movement invented by American author L. Ron Hubbard. Defined as a cult, a business, or a new religious movement, about 25,000 followers in the US (in 2008), 2,300 followers in England (2011), and 1,700 in Canada (2011) and Australia (2016) followed the practice.

However, the Church of Scientology would place her in special projects, vetting her as a potential wife for Tom Cruise with dozens of other women; she briefly dated the actor. Later she left the Church and called herself a non-practicing Muslim in October 2014.
