 The picture was Welles's first feature film.
 Nominated for Academy Awards in nine categories, it won an Academy Award for Best Writing (Original Screenplay) by Herman J. Mankiewicz and Welles.
 Considered by many critics, filmmakers, and fans to be the greatest film of all time, "Citizen Kane" was voted as such in five consecutive British Film Institute "Sight & Sound" polls of critics, until it was displaced by "Vertigo" in the 2012 poll.
 It topped the American Film Institute's 100 Years ... 100 Movies list in 1998, as well as its 2007 update.

"Raising Kane" is a 1971 book-length essay by American film critic Pauline Kael, in which she revived controversy over the authorship of the screenplay for the 1941 film "Citizen Kane".
 Kael celebrated screenwriter Herman J. Mankiewicz, first-credited co-author of the screenplay, and denigrated the contributions of Orson Welles, who co-wrote, produced and directed the film, and performed the lead role.
 The 50,000-word essay was written for "The Citizen Kane Book" (1971), as an extended introduction to the shooting script by Mankiewicz and Welles.
 It first appeared in February 1971 in two consecutive issues of "The New Yorker" magazine.
 In the ensuing controversy Welles was defended by colleagues, critics, biographers and scholars, but his reputation was damaged by its charges.
 The essay was later discredited after Welles's contributions to the screenplay were documented and Kael's own scholarship was called into question.
