Elle Fanning is expanding her partnership with Civic Center Media/MRC Television, which currently houses Fanning's Hulu series The Great.

Fanning has teamed up with her sister, Dakota Fanning, to launch their own production company Lewellen Pictures. The Fanning sisters plan to develop feature films as well as television series and other content, including podcasts.

Their first production venture will be a TV series adaptation of Megan Miranda's bestselling novel The Last House Guest , which centres on an intimate friendship between two girls who fall violently in love with each other’s differences, which, in the end, create doubt, betrayal and tragedy. Sarah Walker (The Secrets She Keeps) will write and executive produce the series.

“Elle has brought such perspective and thoughtfulness as an executive producer on The Great,” said Elise Henderson, President of MRC Television. “We are excited by the vision she and Dakota have for Lewellen Pictures and for MRC Television to provide a home for the stories they will tell.”

Fanning recently received a Golden Globe nomination for her work on The Great, as well as starred in Sally Potter's The Roads Not Taken and Netflix's All The Bright Places. She also executive produced the latter.

Dakota Fanning was recently seen in Quentin Tarantino's Once Upon A Time In Hollywood . The siblings will star together for the first time in a feature film called The Nightingale, for director Melanie Laurent.

“We are thrilled to be launching this company together and to be teaming up with MRC who have been excellent partners on The Great. Our goal is to tell stories, through comedy and drama, which are authentic to the human experience, and not just from our own perspective,” said the Fannings in a joint statement. “We also want to create content that we wouldn’t be able to make just as actors. We can learn so much when we look outside our specific points of view. We have been fortunate to work with many brilliant storytellers and hope to continue that track while also providing opportunities for many more.”
