HBO has officially ended its sessions with “In Treatment.”Intreatment10_10

Series, which ran for three seasons on the pay cabler, will not go forward with a fourth. “In Treatment” was based on an Israeli format in which a psychologist saw a range of clients, as well as seeing his own therapist. The Israeli version ran for only two seasons and the HBO version used the same storylines.

What made the show unique was its rotating cast as well as having a new showrunner every year. Gabriel Byrne appeared in each season as Dr. Paul Weston, who conducted therapy out of his home office. Byrne won the Golden Globe in 2009.

Showrunners for final season were Anya Epstein and Dan Futterman. They exec produced with Stephen Levinson, Mark Wahlberg, Paris Barclay and Hagai Levi. The season one showrunner was Rodrigo Garcia, with Warren Leight coming aboard for the second season.

Levi created the show in Israel and remained an exec producer for the show’s U.S. run. Noa Tishby, who was a co-exec producer in the third season, was instrumental in bringing the show from Israel to America. She introduced the project to Levinson, who had a working relationship with HBO at the time with “Entourage.”

The series helped launch the career of Oz actress Mia Wasikowska. In the first season, she played a gymnast who had an inappropriate relationship with her coach and had family issues. Glynn Turman and Dianne Wiest won Emmys for their perfs in the show’s first season as well.

Byrne, who was twice Emmy nominated and appeared in all 121 episodes, said the role was demanding in that it was often difficult to memorize long stretches of dialogue in a short amount of time.

“In Treatment” was never a ratings winner, drawing only 259,000 viewers for its season three premiere. However, HBO execs felt the series was creatively strong enough to run three seasons.
