‘MANK’ AND THE DEATH OF THE MOVIEGOING EXPERIENCE If last Thursday marked a movie milestone, it’s interesting that “Mank” began streaming on Netflix the very next day. A beautifully shot homage to old Hollywood, it stars Gary Oldman as the alcoholic screenwriter Herman Mankiewicz, engaged in the creation of the 1941 masterpiece “Citizen Kane.” Or at least its first draft. While many have marveled at the audacity of the young Orson Welles (Tom Burke) to take on press baron William Randolph Hearst (Charles Dance), it was Mankiewicz who was really biting the hand that fed him. He’s seen in flashbacks as a frequent dinner guest at Hearst’s San Simeon mansion and a friend and confidant to Hearst’s lover, Marion Davies (Amanda Seyfried).
