Gabriel Byrne is set to star in the new drama, In Treatment for HBO.

The project, based on the popular and critically acclaimed Israeli series, centers on a therapist (Byrne) who is calm, smooth, insightful and nonconfrontational with his patients but turns into a testy, self-doubting man full of barely concealed anger when he is a patient seeing his own shrink. The Hollywood Reporter notes Australian newcomer Mia Wasikowska is also joining the show as a gymnast with dreams to go to the Olympics, and is receiving psychiatric treatment.

In Treatment has already received a 5-episode run; it's set to air later this year on HBO.
