Its Terrific!

The film X engendered controversy (and efforts at suppression in early 1941 through intimidation, blackmail, newspaper smears, discrediting and FBI investigations) before it premiered in New York City on May 1, 1941, because it appeared to fictionalize and caricaturize certain events and individuals in the life of  Y - a powerful newspaper magnate and publisher. The film was accused of drawing remarkable, unflattering, and uncomplimentary parallels to real-life. The notorious battle was detailed in Thomas Lennon's and Michael Epstein's Oscar-nominated documentary The Battle Over X (1996), and it was retold in HBO's cable-TV film RKO 281 (1999) (the film's title referred to the project numbering for the film by the studio, before the film was formally titled).
The gossip columnist Louella Parsons persuaded her boss Y that he was being slandered by RKO and X when it was first previewed, so the Y-owned newspapers (and other media outlets) pressured theatres to boycott the film and also threatened libel lawsuits. Y also ordered his publications to completely ignore the film, and not accept advertising for other RKO projects.
