The 'Mamma Mia!' star and the 'Tolkien' actress are joining Tuppence Middleton and Gary Oldman in the cast ensemble of the 'Panic Room' director's first feature film since 2014's 'Gone Girl'.
David Fincher has recruited Amanda Seyfried, Lily Collins, and Tuppence Middleton for his new movie, based on his father's script about Hollywood screenwriter Herman J. Mankiewicz.
Gary Oldman will play the writer, who co-wrote "Citizen Kane" with Orson Welles, in "Mank", which marks Fincher's first feature film since 2014's "Gone Girl".
Arliss Howard, Charles Dance, "Gone Girl" 's Jamie McShane, and Sam Troughton will also appear in "Mank", which like "Citizen Kane", will be shot in black and white.
