Acclaimed 2024 Edinburgh International Festival production, The Fifth Step, by David Ireland, is heading to London’s West End this summer with Jack Lowden, best known as River Cartwright in the Apple TV spy drama Slow Horses, reprising his performance as Luka, alongside the award-winning Martin Freeman, star of The Office and Sherlock, who joins the production as James, the part originally played by Sean Gilder in Ireland’s funny, unflinchingly and honest drama about addiction, masculinity and faith.
