A new documentary opening October 9 in theaters examines forensic analysis of a daguerreotype that surfaced in 2020, which some believe shows Joseph Smith. "Brother Joseph Again: Exploring the Visual Image of Joseph Smith Jr." presents experts from both sides of the authentication debate.

No confirmed photograph of the LDS Church founder has ever been validated. The daguerreotype's emergence sparked immediate controversy among historians and church members. The film uses modern forensic techniques to evaluate the image's authenticity, though the documentary includes voices arguing both for and against the photograph's legitimacy.
