Donald Glover and Maya Erskine's exit from the series after the first season allows the show to adopt an anthology format and introduce a new titular couple.According to Deadline's exclusive report, Anora actor Mark Eydelshteyn and Yellowjackets star Sophie Thatcher were initially in talks to play John and Jane Smith, respectively, in the second season in February 2025. After naming the new titular couple, the show received a $22.4 million tax credit in March after the plan to relocate the series from New York to Los Angeles.

However, casting details were never finalized, and the only confirmed cast members are still Eydelshteyn and Thatcher. With Sloane's departure, Mr. & Mrs. Smith season 2 doesn't currently have a showrunner or a final cast list.Further complicating matters is the tax credit from the California Film Commission, per The Hollywood Reporter.
