In 2020, Oldman took on the role of 'Citizen Cane' screenwriter Herman J. Mankiewicz in Mank. The role scored him several nominations including the Oscar for Best Actor in a Leading Role. In 2017, Oldman delivered a resounding performance as former British Prime Minister Winston Churchill in Darkest Hour, earning Golden Globe and Oscar wins for Best Actor. Despite previously dismissing the Globes as "meaningless," he was more gracious upon hearing his name called during the 2018 ceremony, saying, "I feel very humbled and surprised to have been asked to this stage."
