*A Motion Picture Association of America title registration bureau arbitration ruled Tuesday that The Weinstein Co. could not use the title “The Butler” on its upcoming film, due to be released Aug. 16, because that previously served as the title of a 1916 short film that now belongs to the Warner Bros. library.

Harvey Weinstein, however, will not go down without a fight for his Lee Daniels film. According to The Hollywood Reporter, he has enlisted high-powered attorney David Boies, who most recently prevailed in a Supreme Court challenge to California’s gay marriage ban, Proposition 8.

The Weinstein Co. issued a response statement from Boies that said, “The suggestion that there is a danger of confusion between The Weinstein Co.’s 2013 feature movie and a 1917 [sic] short that has not been shown in theaters, television, DVDs, or in any other way for almost a century makes no sense. The award has no purpose except to restrict competition and is contrary to public policy.”

The Hollywood Reporter’s Tim Appelo writes:

While the titles of works of art cannot be copyrighted (nor, in general, trademarked), the MPAA maintains the Title Registration Bureau, which is a voluntary central registration entity for titles of movies intended for U.S. theatrical distribution to prevent public confusion over films with similar titles. In order to register titles, companies subscribe to the registry and are bound by the bureau’s rules, which prescribe procedures for registering titles and handling any related disputes.

Usually, when one company wants to use a title to which another studio already has a claim, the two engage in some behind-the-scenes horse-trading, but that didn’t happen in this case and instead the issue went to arbitration. The arbitration board said that The Weinstein Co. has to change the name of the film immediately, saying “TWC made continuous use of the unregistered title The Butler in willful violation of the TRB rules.”

According to one source, Warners didn’t make any case at the arbitration that it intended to use the title The Butler — or that it had it in use. Instead, it chose to stand on precedent, arguing that The Weinstein Co., which is a signatory to the TRB though not a member of the MPAA, hadn’t followed the established rules.

The ruling creates an immediate problem for The Weinstein Co., which has already begun promoting the film, which stars Forest Whitaker and is based on the true story of Eugene Allen, who worked at the White House for 34 years, retiring as head butler in 1986. The film also stars Oprah Winfrey and a star-studded cast that includes Robin Williams, Jane Fonda, Liev Schreiber and John Cusack and is being positioned as a potential awards contender.
