Development In 2018, it was reported that a television series adaptation of
The Rainmaker was being developed by
Michael Seitzman and Jason Richman for
Hulu with
ABC Studios. The series was slated to be one of the first in a larger
shared universe based on the works of
John Grisham, alongside an adaptation of his 2015 novel
Rogue Lawyer; both series would have been produced concurrently and contain an intertwining storyline with shared characters, and would have been able to be watched on a parallel or standalone basis. Neither series went forward with Hulu. After signing a
first-look deal with
Blumhouse Television in 2021, Seitzman began developing
The Rainmaker as a standalone project with the studio. Blumhouse would offer it to
Lionsgate Television, and
USA Network would order it to series in June 2024. It was reported that the series was considered part of a pivot by the channel back towards producing original dramas in the vein of its previous "blue sky" era.
