Faulkner estate claims that quoting his novels in films is both a trademark and copyright infringement

A reader writes, "A character in Woody Allen's Midnight in Paris quoted nine words from William Faulkner, with attribution. Faulkner Literary Rights LLC has responded a year later with a lawsuit alleging copyright infringement and attempts to deceive viewers into thinking Requiem for a Nun is a game for the PS3. Or something." The suit's major claims seem to turn on trademark (though there are copyright claims in there, too): the Faulkner estate claims that a movie that quotes Faulkner and has a character who meets various historical people (including Faulkner) "is likely to cause confusion, to cause mistake, and/or to deceive the infringing film's viewers as to a perceived affiliation, connection or association between William Faulkner and his works, on the one hand, and Sony, on the other hand."
