HBO announced Friday that it has ordered a third season of the drama “In Treatment”, which stars Gabriel Byrne as therapist Paul Weston.

A third season had been in some doubt, as Byrne has said in interviews that he finds the role (which he plays very well) quite challenging. That’s understandable; his character is in almost every scene and much of his work involves reacting to and working through thorny issues with the sometimes challenging patients in his care.

The show is changing head writers again, as it has done every season so far. Anya Epstein of HBO’s “Tell Me You Love Me” and Danny Futterman (“Capote”) will take over from Season 2 showrunner Warren Leight.

The show goes into production early next year in New York.
