MOVIE PREMIERE: The other day, TCM televised 1941’s Citizen Kane. Today, Netflix premieres a new movie about the making of that classic Orson Welles film. Welles starred in the title role, directed the film, and is credited with co-writing the screenplay. This new film, though, focuses on the other credited co-writer: Herman L. Mankiewicz. Gary Oldman stars as Mankiewicz, a.k.a. Mank, and the other players in Mank include Charles Dance as tycoon William Randolph Hearst
