In Mank (2020), Orson Welles put Mank under contract to write the first draft screenplay for "Citizen Kane" under the supervision of John Houseman. Mank is a former partner of Orson Welles at the Mercury Theatre. At his new residence, Mank recieved a phone call from Orson Welles:
Orson Welles: I thought I told you, Mank. I have final cut, final everything. There are no studio notes. We'll have no one but ourselves to blame.
Actually Orson Welles gave Mank 60 days time to complete the draft. Then how did Orson Welles prepare final cut without any draft?
