Tony Shalhoub is set to appear in a recurring guest-starring role on CBS’s upcoming drama series “Einstein,” according to reports from Variety and Deadline. The casting reunites Shalhoub with “Monk” creator Andy Breckman, who developed “Einstein” from a German format and serves as a creator and executive producer on the CBS project. Both outlets describe “Einstein” as part of CBS’s 2026–27 broadcast season and report that the series is currently in production. Shalhoub previously starred as Adrian Monk for eight seasons on USA Network’s “Monk” and also appeared in the follow-up TV movie “Mr. Monk’s Last Case.” Deadline adds that Breckman is joined by Randy Zisk among the show’s executive producers, and it identifies Shalhoub’s additional credits, including “The Marvelous Mrs. Maisel.” The new reports do not specify the character Shalhoub will play in “Einstein.”
