Brazil probe document links 'Mário' to Dark Horse producer; identity unconfirmed

A seized document in a Brazilian investigation lists 'Mário' as a partner of the 'Dark Horse' producer in the USA, but lacks a surname. Mário Frias, a screenwriter and executive producer of the film, is a possible match, though this is unconfirmed. The development suggests a potential legal or investigative angle involving the film's production.
