Calling all die-hard Metallica fans! You know who you are, and one of us may be one of them! The iconic band issued a casting call earlier this week for “superfans” to potentially feature in an upcoming documentary. The filmmakers are specifically interested in individuals with “big personalities, unique characters, and extraordinary stories, those who consider themselves real ‘fifth members’ of Metallica.” No matter your background or experiences, all fans are encouraged to participate in this project. The documentary is a joint production by Metallica and Mercury Studios in collaboration with Universal Music Group.
