In Treatment is an American HBO drama, produced and developed by Rodrigo Garcia, about a psychologist, 50-something Dr. Paul Weston, and his weekly sessions with patients, as well as those with his own therapist at the end of the week. The program, which stars Gabriel Byrne as Paul, debuted on January 28, 2008, as a five-night-a-week series. The series' executive producer and principal director was Paris Barclay, who directed 35 episodes, the most of any director on the series, and the only director who directed episodes in all three seasons. The program's format, script and opening theme are based on, and are often verbatim translations of the Israeli series BeTipul, created by Hagai Levi, Ori Sivan and Nir Bergman. After winning critical acclaim and numerous honors, including Emmy, Golden Globe and Writers Guild awards, In Treatment returned for a second season, premiering on April 5, 2009. The second season built on the success of the first, winning a 2009 Peabody Award. The third and final season premiered on October 26, 2010, for a seven-week run, with four episodes per week.
