ROLAND EMMERICH’S film “Anonymous,” which opens next week, “presents a compelling portrait of Edward de Vere as the true author of Shakespeare’s plays.” That’s according to the lesson plans that Sony Pictures has been distributing to literature and history teachers in the hope of convincing students that Shakespeare was a fraud. A documentary by First Folio Pictures (of which Mr. Emmerich is president) will also be part of this campaign.

So much for “Hey, it’s just a movie!”

The case for Edward de Vere, 17th Earl of Oxford, dates from 1920, when J. Thomas Looney, an English writer who loathed democracy and modernity, argued that only a worldly nobleman could have created such works of genius; Shakespeare, a glover’s son and money-lender, could never have done so. Looney also showed that episodes in de Vere’s life closely matched events in the plays. His theory has since attracted impressive supporters, including Sigmund Freud, the Supreme Court justice Antonin Scalia and his former colleague John Paul Stevens, and now Mr. Emmerich.

But promoters of de Vere’s cause have a lot of evidence to explain away, including testimony of contemporary writers, court records and much else that confirms that Shakespeare wrote the works attributed to him. Meanwhile, not a shred of documentary evidence has ever been found that connects de Vere to any of the plays or poems. As for the argument that the plays rehearse the story of de Vere’s life: since the 1850s, when Shakespeare’s authorship was first questioned, the lives of 70 or so other candidates have also confidently been identified in them. Perhaps the greatest obstacle facing de Vere’s supporters is that he died in 1604, before 10 or so of Shakespeare’s plays were written.

“Anonymous” offers an ingenious way to circumvent such objections: there must have been a conspiracy to suppress the truth of de Vere’s authorship; the very absence of surviving evidence proves the case. In dramatizing this conspiracy, Mr. Emmerich has made a film for our time, in which claims based on conviction are as valid as those based on hard evidence. Indeed, Mr. Emmerich has treated fact-based arguments and the authorities who make them with suspicion. As he told an MTV interviewer last month when asked about the authorship question: “I think it’s not good to tell kids lies in school.”
