Millie Bobby Brown, Rachel Brosnahan & AGBO Developing Supernatural Series ‘Prism’ At Netflix
EXCLUSIVE: Millie Bobby Brown (Stranger Things, Enola Holmes) will star in and executive produce the new series Prism, currently in development at Netflix, sources close to the production reveal to Deadline. Rachel Brosnahan and AGBO, in their third project with the streamer, will also executive produce.
Etan Frankel (Shameless, Joe vs. Carole) has been tapped as showrunner.
Netflix declined comment.
Brown will play Cassie, a woman with the unique ability to communicate with apparitions, who must uncover the cause of a newly discovered phenomenon that causes “visitors” (ghosts) to appear all over the world before it’s too late.
Prism is based on the short story of the same name that was an Assemble Original featured in the magazine Assemble Artifacts, and was developed in-house with writer Nick Shafir, who will co-produce. Assemble Media is attached to produce.
Executive producers include Brown through her PCMA banner; Brosnahan and Russell Kahn via Scrap Paper Pictures; Anthony Russo, Joe Russo, Angela Russo-Otstot, Scott Nemes and Alessandra Maman on behalf of AGBO; and Jack Heller and Caitlin de Lisser-Ellen of Assemble Media.
We understand that if the project goes to series, starring in Prism will not prevent Brown from keeping her commitments to previously announced projects. This is her second collaboration with AGBO, following her lead role in Netflix’s The Electric State, the Russo brothers’ most recent film.
Prism expands Brown’s long and successful collaboration with Netflix that began with her starring role as Eleven in the smash hit Stranger Things, due to conclude its run with a fifth season to be released in three parts in November and December. Also hugely popular are Brown’s Enola Holmes franchise films, two of which are currently available to stream with a third expected to premiere in 2026.
Brosnahan’s breakout role was in Netflix’s House of Cards; she appeared in an episode of Orange is the New Black and starred in the streamer’s film Saturn Return alongside Charles Melton and Will Poulter. She is best known for playing the lead in Prime Video’s Emmy-winning period dramedy The Marvelous Mrs. Maisel. She most recently played Lois Lane in James Gunn’s Superman. Up next, Brosnahan will star in and executive produce the sophomore season of Apple TV’s Presumed Innocent.
AGBO is currently producing Marvel’s Avengers: Doomsday in London, to be followed up by Avengers: Secret Wars (2027), with the Russos directing. The studio recently released The Electric State for Netflix, which premiered as the platform’s No. 1 film, and wrapped The Bluff for Amazon MGM and The Whisper Man for Netflix. Citadel Season 2 for Prime Video is currently in post-production. AGBO also collaborated with Netflix on The Gray Man (2022) feature starring Ryan Gosling, Chris Evans and Ana de Armas.
Frankel is currently an executive producer on Big Mistakes for Netflix, with Dan Levy writing and attached to star. Most recently, he spent four years in an overall deal at UCP. While there, he was the creator/showrunner of Joe vs. Carole for Peacock. Previously, he was an EP on Get Shorty for Epix/MGM, two seasons on Animal Kingdom and on Showtime’s Shameless, where he wrote for seven seasons.
