Robert Downey, Jr. is helping to develop a new drama series based on Michael Crichton’s sci-fi novel Sphere.
The Avengers star and his producer wife Susan Downey have joined forces with Westworld writer and executive producer Denise The, among others, for the HBO project.
Adapted by The, Sphere will take viewers on a deep dive into the ocean to examine a newly-discovered alien spacecraft.
The 1987 book was previously turned into a film starring Dustin Hoffman, Sharon Stone, and Samuel L. Jackson. Barry Levinson directed and produced the 1998 release.
