Witness for the Prosecution has been gripping West End audiences since 2017, and its power shows absolutely no sign of fading. Now in its fifteenth cast, the production is one of the most celebrated theatrical experiences in London, with almost every performance selling out. Set inside the spectacular historic Council Chamber of London County Hall on the South Bank, the show places audiences directly in the courtroom as the case unfolds around them.

Owen leads the company as Leonard Vole, a man accused of murdering a widow to inherit her wealth. It is a role that demands presence, nuance, and the ability to hold a room, and Owen does all three. Directed by Lucy Bailey, whose credits include Death on the Nile and Murder on the Orient Express, the production weaves Christie's story of justice, passion, and betrayal into a thrilling night of theatre that stays with you long after the curtain falls.

"Making my West End debut is genuinely a dream come true. I have wanted to prove myself on stage for so long, and to do it in a production like this, playing a character as complex and compelling as Leonard Vole, is everything. I am so grateful for the opportunity and so proud to be part of something this special."
