Joe Alwyn and Hugh Laurie Complete Cast of BBC/MGM+ Espionage Series 'Legacy of Spies'

The cast of the forthcoming espionage drama 'Legacy of Spies' has reached completion with the addition of two major stars. Variety revealed on Wednesday, June 10, that Joe Alwyn, 35, and Hugh Laurie, 66, are joining the BBC/MGM+ series as the final ensemble members.

Alwyn will portray MI6 agent Jim Prideaux, while Laurie takes on the role of his superior, Control. The eight-part thriller draws from John le Carré's literary catalog, blending elements from multiple works including The Spy Who Came in from the Cold, Tinker Tailor Soldier Spy, and The Honorable Schoolboy, alongside additional unpublished material.

Rounding out the supporting cast are Anjana Vasan, Charlotte Ritchie, Lee Ross, James McArdle, John Dagleish, and Adam Hugill.

The project, initially announced in March 2025, brings together an impressive lineup of established talent. Matthew Macfadyen will headline as intelligence veteran George Smiley, with Charlie Hunnam cast as field operative Alec Leamas. Daniel Brühl joins as Josef Fiedler and Dan Stevens as Bill Haydon.

The Ink Factory, holder of the rights to le Carré's extensive catalog, is producing the series, while Fifth Season handles distribution across Europe and the United States.
