A fascinating look about what supposedly went into 'Citizen Kane'.
'Mank', a biopic about screenwriter Herman J. Mankiewicz, is a very good watch. A lot goes on and it's pretty much all interesting to see, admittedly you'd need to have seen the 1941 film. I like that they done this in a non-linear format and in black-and-white, à la in '41.
Kudos to the cast. Gary Oldman (Herman) is impressive, I did feel he was overacting - likewise with Amanda Seyfried (Marion) - just a little bit in parts but for the vast, vast majority he (and she) is top notch. Arliss Howard (Mayer), Lily Collins (Rita) and a few others are also pleasing to watch.
