The dispute between Boston College spokesman Jack Dunn and the makers of “Spotlight” is escalating. “Spotlight,” as you no doubt know, is a movie about The Boston Globe’s Pulitzer Prize-winning reporting on the pedophile-priest scandal in the Catholic Church.

For the past few days, starting with a Kevin Cullen column in Sunday’s Globe, Dunn has been making media appearances claiming that he was falsely portrayed in the movie as uncaring toward victims at BC High School. The filmmakers have pushed back hard, arguing that the depiction of Dunn is accurate and that it was vetted by Globe reporters Walter Robinson and Sacha Pfeiffer.

According to an exchange of letters that I obtained this evening, Dunn’s lawyers are accusing the filmmakers of portraying Dunn in a way that is “defamatory” as well as “false, malicious and fabricated.” The letter on behalf of Dunn, addressed primarily to screenwriters Tom McCarthy and Joshua Singer (McCarthy is also the director), says in part:

In general, the film, in dramatic fashion, divides the individuals it depicts into those who heroically searched for the truth about the horrific sexual abuse of children by members of the clergy and those who sought to suppress facts about the abuse. In a critical scene in the film, which is nearly entirely fabricated, Spotlight squarely and falsely places Mr. Dunn in the category of those who actively attempted to interfere with and thwart the efforts of the Boston Globe reporters to unearth and report on the abuse scandal.

In their answer, the filmmakers’ lawyers “respectfully, but vigorously, disagree with your allegation that the film defames Mr. Dunn.” Here’s a key excerpt:

Most importantly, the film’s portrayal of Mr. Dunn is substantially true. It is based on the recollections of Walter Robinson and was vetted by him and Sacha Pfeiffer. Mr. Dunn’s overarching concern for Boston College High School (and Boston College) is reflected in contemporaneous and later media accounts. Indeed, there is no evidence that Mr. Dunn was an outspoken advocate for transparency or accountability before the Boston Globe broke the story, or that he came forward on his own to initiate an investigation into abuse at BC High before the Globe’s coverage forced the school to act.

I am posting these rather lengthy documents in the interest of putting them before the public in advance of what could be a significant legal battle.

Update: The Globe has now published an article on the dispute.
