"Citizen Kane" has been called the most influential film of all time. Richard Corliss has asserted that Jules Dassin's 1941 film "The Tell-Tale Heart" was the first example of its influence and the first pop culture reference to the film occurred later in 1941 when the spoof comedy "Hellzapoppin"' featured a "Rosebud" sled. The film's cinematography was almost immediately influential and in 1942 "American Cinematographer" wrote "without a doubt the most immediately noticeable trend in cinematography methods during the year was the trend toward crisper definition and increased depth of field."
