Monica Barbaro in final negotiations to join Bradley Cooper and Margot Robbie for Warner Bros. ‘Ocean’s’ prequel

Warner Bros. is moving forward on an “Ocean’s” prequel project led by director and producer Bradley Cooper, and Oscar nominee Monica Barbaro is reportedly in final negotiations to join the film’s principal cast, according to an exclusive report from Deadline published June 30, 2026.

The report says the prequel would star Cooper alongside Margot Robbie and Wagner Moura, and that Barbaro is expected to take a role in the ensemble if the talks conclude successfully. Deadline also characterizes Barbaro as being “bound” to join Cooper’s crew, with negotiations described as reaching the final stage rather than being exploratory.

Deadline ties the project to a specific calendar and distribution plan, stating the movie is dated for June 25, 2027 and that it is readying for a shoot. The same report places Cooper in both directing and producing roles, indicating he is involved in both creative and production decision-making for the Warner Bros. release.

Beyond the casting, Deadline’s report frames the project as part of the studio’s continued development of the “Ocean’s” brand, which has historically relied on major stars and a large-scale ensemble structure. The prequel concept, as described in the report, expands the franchise beyond its original characters while maintaining its core premise of coordinated, heist-style crew dynamics.

The report does not provide details on character names, plot specifics, or the exact role Barbaro would play. It also does not specify whether any additional performers have been formally locked beyond the cast group it identifies, leaving room for further casting announcements as production approaches.

For Barbaro, the reported talks represent a new franchise-casting opportunity following her Oscar-nominated recognition, with Deadline describing her as an Oscar nominee at the time the negotiations are underway. For Cooper and the filmmakers, the casting update suggests Warner Bros. is working to assemble a multi-star roster for a tentpole release scheduled for mid-2027.

The next steps, based on Deadline’s description, are largely contractual. If negotiations with Barbaro conclude, Warner Bros. would be expected to move from final discussions into formal casting announcements and production planning, including confirming roles, finalizing shooting schedules, and expanding the supporting cast as the release date nears.
