Matt Ryan Lines Up Broadway Role Opposite Keira Knightley in 'Therese Raquin'

Matt Ryan

The 'Constantine' star joins the cast along with Tony winners Gabriel Ebert and Judith Light, and previously announced lead Knightley in the title role.

Keira Knightley's Therese Raquin has found the two opposing points of her turbulent romantic triangle.

Gabriel Ebert, a Tony winner for the musical Matilda, and Matt Ryan, a London theater regular best known to U.S. audiences for his role on NBC's Constantine, have joined the cast of the Roundabout Theatre Company Broadway production, premiering in the fall.

In a new stage adaptation by Helen Edmundson of Emile Zola's classic novel, Ebert will play the weak and selfish Camille, married to Therese, played by previously announced lead Knightley. Ryan is cast as Therese's childhood friend Laurent, who re-enters her life, accompanied by passionate feelings that spin out of control.

The production marks the Broadway debut for Knightley, while Ryan was seen previously in 2009 in Hamlet, starring Jude Law.

Also joining the cast is Broadway favorite Judith Light, who won back to back Tony Awards in 2012 and 2013 for Other Desert Cities and The Assembled Parties, respectively. Light will play Therese's controlling mother-in-law.

Directed by Evan Cabnet, the play is part of Roundabout's 50th anniversary season. It starts previews Oct. 1 at Studio 54, with official opening set for Oct. 29.

Also on the starry season slate at Roundabout to celebrate the golden milestone is Eugene O'Neill's Long Day's Journey Into Night, with Jessica Lange, Gabriel Byrne and John Gallagher Jr.; Harold Pinter's Old Times, with Clive Owen, Eve Best and Kelly Reilly; Andrea Martin in Michael Frayn's Noises Off; and Laura Benanti and Josh Radnor in the musical revival She Loves Me.
