The upcoming thriller Dear David, starring Justin Long, Augustus Prew (whose upcoming exciting projects include Amazon's upcoming Lord of the Rings series), and Andrea Bang (best known for her performance in ABC's A Million Little Things), has just finished filming. The film, based on a viral ghost story posted on Twitter by a BuzzFeed employee, is being produced by BuzzFeed Studios and Lionsgate.Augustus Prew will be playing the role of the protagonist Adam Ellis, and Justin Long will be the head of BuzzFeed.The "Dear David" story took Twitter by storm when it debuted in the summer of 2017 and continued through the winter of 2018. It was a thread started by former Buzzfeed employee Adam Ellis and spanned over countless spine-tingling tweets. While many believe it to be a hoax, it has undoubtedly gone on to become one of the first and the most successful urban legends on Twitter. Basically, Ellis began a thread about him being haunted by the ghost of a dead child who was apparently bent on killing him.[EMBED_TWITTER]https://twitter.com/adamtotscomix/status/894582846907482113[/EMBED_TWITTER]The rather lengthy thread soon got the attention of the Twitter community and it went viral, gaining Ellis more than a million followers on the platform. According to the thread, he first saw "Dear David" in a dream, following which the figure apparently made its way into the "real world." Ellis' thread was utterly enticing, and many of his followers kept suggesting that he should "cash in" this story and make a film out of it.Finally, back in November, Lionsgate and BuzzFeed announced the film version of this "urban legend."Dear David is a terrifyingly creepy and sensational story that will translate perfectly to the big screen. It hits our goal of reaching global Millennial and Gen Z audiences by elevating contemporary, authentic new voices.- Lauren Bixby, Vice President, Co-Productions and Acquisitions, Lionsgate.Richard Alan Reid, Head of Global Content & Head of BuzzFeed Studios, added: Ellis's story captivated audiences across the Internet and built a passionate, global fan base that has been waiting for the film adaptation. We can't wait to bring this highly anticipated, harrowing tale to the big screen next year.Although Dear David was originally meant to be produced under the banner of New Line Cinema, with Dan Lin as the producer, it ended up being Lionsgate and BuzzFeed's third collaboration after 1UP and My Fake Boyfriend. Richard Alan Reid of BuzzFeed will be producing the film along with Jason Moring, Michael Philip, and Naysun Alae-Carew. New Line's Dan Lin is still a significant part of the project, as he will be presiding as the Executive Producer.
