More than 400 Hollywood creative leaders signed an open letter to the Trump White Houses Office of Science and Technology Policy, urging the administration to not roll back copyright protections at the behest of AI companies.The filmmakers, writers, actors, musicians and others which included Ben Stiller, Mark Ruffalo, Cynthia Erivo, Cate Blanchett, Cord Jefferson, Paul McCartney, Ron Howard and Taika Waititi were submitting comments for the Trump administrations U.S. AI Action Plan. The letter specifically was penned in response to recent submissions to the Office of Science and Technology Policy from OpenAI and Google, which asserted that U.S. copyright law allows (or should allow) allow AI companies to train their system on copyrighted works without obtaining permission from (or compensating) rights holders.Related StoriesWe firmly believe that Americas global AI leadership must not come at the expense of our essential creative industries, the letter says in part. The letter claims that AI companies are asking to undermine this economic and cultural strength by weakening copyright protections for the films, television series, artworks, writing, music and voices used to train AI models at the core of multibillion-dollar corporate valuations.Popular on VarietyThe letters signatories include: Ben Stiller, Mark Ruffalo, Guillermo del Toro, Natasha Lyonne, Paul McCartney, Cynthia Erivo, Cate Blanchett, Phoebe Waller-Bridge, Cord Jefferson, Bette Midler, Cate Blanchett, Ava Duvernay, Paul Simon, Aubrey Plaza, ngel Manuel Soto, Ron Howard, Taika Waititi, Ayo Edebiri, Joseph Gordon-Levitt, Lily Gladstone, Sam Mendes, Brit Marling, Janelle Mone, Bryn Mooser, Rian Johnson, Paul Giamatti, Maggie Gylenhall, Alfonso Cuaron, Olivia Wilde, Judd Apatow, Kim Gordon, Chris Rock and Michaela Coel.The letter says Google and OpenAI are arguing for a special government exemption so they can freely exploit Americas creative and knowledge industries, despite their substantial revenues and available funds. There is no reason to weaken or eliminate the copyright protections that have helped America flourish. OpenAI alleged in its OSTP submission (at this link) that the U.S. copyright codes fair use doctrine promotes AI development and the company proposed that the U.S. take steps to ensure that our copyright system continues to support American AI leadership and American economic and national security, including working to prevent less innovative countries from imposing their legal regimes on American AI firms and slowing our rate of progress.Google, in its submission (at this link), advocated for balanced copyright rules, such as fair use and text-and-data mining exceptions, which the company said has been critical to enabling AI systems to learn from prior knowledge and publicly available data, unlocking scientific and social advances. These exceptions allow for the use of copyrighted, publicly available material for AI training without significantly impacting rightsholders and avoid often highly unpredictable, imbalanced and lengthy negotiations with data holders during model development or scientific experimentation.Here is the full text of the letter from the Hollywood signatories:Hello Friends & Strangers. As you may be aware there has recently been a recommendation by OpenAI & Google to the current US Administration that is gaining alarming traction to remove all legal protections & existing guardrails surrounding copyright law protections for the training of Artificial Intelligence. This rewriting of established law in favor of so-called Fair Use was in need of an initial response by 11:59 PM ET Saturday, so we have submitted an initial letter with the signatories we had at that time. We are now continuing to accept signatures for an amendment to our initial statement. Please feel free to forward this to anyone you think may be invested in the ethical maintenance of their intellectual property. You can add your name and whatever guilds or unions or description of self you feel appropriate, but please do not edit the letter itself. Thank you so much for kicking this out wide on a Saturday Night!Hollywoods Response to the Administrations Artificial Intelligence Action Plan and necessity that copyright law be upheld.We, the members of Americas entertainment industry representing an intersection of cinematographers, directors, producers, actors, writers, studios, production companies, musicians, composers, costume, sound & production designers, editors, gaffers, union and Academy Members, and other industrious, creative content professionals submit this unified statement in response to the Administrations request for input on the AI Action Plan.We firmly believe that Americas global AI leadership must not come at the expense of our essential creative industries. Americas arts and entertainment industry supports over 2.3M American jobs with over $229Bn in wages annually, while providing the foundation for American democratic influence and soft power abroad. But AI companies are asking to undermine this economic and cultural strength by weakening copyright protections for the films, television series, artworks, writing, music, and voices used to train AI models at the core of multi-billion dollar corporate valuations.Make no mistake: this issue goes well beyond the entertainment industry, as the right to train AI on all copyright-protected content impacts all of Americas knowledge industries. When tech and AI companies demand unfettered access to all data and information, theyre not just threatening movies, books, and music, but the work of all writers, publishers, photographers, scientists, architects, engineers, designers, doctors, software developers and all other professionals who work with computers and generate intellectual property. These professions are the core of how we discover, learn, and share knowledge as a society and as a nation. This issue is not just about AI leadership or about economics and individual rights, but about Americas continued leadership in creating and owning valuable intellectual property in every field.It is clear that Google (valued at $2Tn) and OpenAI (valued at over $157Bn) are arguing for a special government exemption so they can freely exploit Americas creative and knowledge industries, despite their substantial revenues and available funds. There is no reason to weaken or eliminate the copyright protections that have helped America flourish. Not when AI companies can use our copyrighted material by simply doing what the law requires: negotiating appropriate licenses with copyright holders just as every other industry does. Access to Americas creative catalog of films, writing, video content, and music is not a matter of national security. They do not require a government-mandated exemption from existing U.S. copyright law.America didnt become a global cultural powerhouse by accident. Our success stems directly from our fundamental respect for IP and copyright that rewards creative risk-taking by talented and hardworking Americans from every state and territory. For nearly 250 years, U.S. copyright law has balanced creators rights with the needs of the public, creating the worlds most vibrant creative economy. We recommend that the American AI Action Plan uphold existing copyright frameworks to maintain the strength of Americas creative and knowledge industries, as well as American cultural influence abroad.
