Ryan Gosling’s Open Invite and Warner Bros. begin early development on “Flintstones” live-action reboot centered on Bamm-Bamm

Warner Bros. is developing a new live-action feature based on The Flintstones, and a report from The Dish describes the project as centering on a grown-up Bamm-Bamm Rubble. The effort is being pursued in early development, according to Deadline, with Ryan Gosling’s production company Open Invite involved through Gosling and his Open Invite producing partner Jessie Henderson.

Deadline reports that the producing team is currently looking for a writer for the film. The move indicates the project is still at the stage where a screenwriter is needed before the story and production timeline can firm up, with no script, casting, or release window described in the reporting.

While the new concept is framed as a Flintstones continuation through Bamm-Bamm’s grown-up perspective, the report does not provide additional creative specifics such as plot direction, genre tone, or whether the film would align with any particular prior adaptation or continuity. The only concrete creative direction included in the report is the adult Bamm-Bamm focus.

The project also sits within Warner Bros.’ broader slate, where the studio has continued to develop legacy properties for film and other formats. In this case, the Deadline report ties the project directly to the Gosling-led Open Invite collaboration and indicates that the writer-search phase is the current priority for moving the development forward.

No information in the report identifies additional production partners, studios beyond Warner Bros., or distribution plans. It also does not name potential cast members or creative leadership beyond the production duo, other than indicating that the filmmakers are in the earliest phase of development.

For families and long-time viewers, live-action remakes and reimaginings of classic animated franchises can raise questions about audience suitability and how original character identities are carried into modern storytelling. The reporting here does not address content targets or rating goals, but it does place the project in the pre-scripting stage where such decisions often begin to take shape after a writer is attached.

The next step described by Deadline is the selection of a writer. Once a writer is hired, the project would typically move from conceptual development to script drafts and formal internal approvals, which would then clarify whether the adult-Bamm-Bamm premise expands into a broader Flintstones story package or remains narrowly centered on that character.
