Lee Sang-yoon to Portray Alan Turing in Acclaimed Play 'Turing Machine'

Actor Lee Sang-yoon has been cast as the lead in the highly anticipated play 'Turing Machine,' scheduled to premiere on January 8, 2026, at the S Theater in the Sejong Center for the Performing Arts, Seoul.

'Turing Machine' brings the life of brilliant British mathematician Alan Turing to the stage. The play has already garnered significant recognition, winning four major awards at France's prestigious Molière Awards, including Best Playwright and Best Play, affirming its artistic merit.

During its Korean premiere in 2023, 'Turing Machine' received rave reviews from both audiences and critics for its intellectually dense performances and innovative four-sided stage design, which maximized interaction between performers and spectators.

Lee Sang-yoon, who is joining the production, is expected to deliver a nuanced portrayal of Turing's complex life, capturing his profound solitude and thoughtful nature through solid inner acting. Alan Turing is renowned as the unsung hero who shortened World War II by cracking the German 'Enigma' code, saving millions of lives, and is also considered a pioneer of modern computer science and artificial intelligence (AI).

Lee Sang-yoon has previously captivated audiences on stage in productions such as 'Last Session,' 'Closer,' and 'Death of a Salesman,' demonstrating his ability to connect deeply with viewers. His casting in this role promises another powerful performance.

The play 'Turing Machine' will run from January 8 to March 1, 2026, at the S Theater in the Sejong Center for the Performing Arts.

Fans are expressing excitement over Lee Sang-yoon's return to the stage, commenting, "Can't wait to see Lee Sang-yoon's acting, as always!
