Comment On Mankiewicz Character
I'm not a film buff, and although I'd seen Citizen Kane years ago in college, I didn't know much of it.
I liked RKO 281. I liked learning of the Herman Mankiewicz through John Malkovich's portrayal. I didn't know such a person existed, but from digging around online it appears that RKO 281 was simply portraying the gist of an actual creative relationship between Welles and Mankiewicz, and then a conflict over authorship. For example:

"Mank became entangled in a storm over the Academy Award winning script for Citizen Kane. Even though Orson Welles initially asserted that he wrote it, the majority of the people who worked on the movie as well as host of researchers are adamant that Mankiewicz deserves the most credit."
I don't have time to dig in and learn the nuances of the controversy, but I liked this HBO movie taking a shot at laying out this and other stories about the making of Citizen Kane. Liev Schreiber was good in this, as were others.
