HBO has renewed “In Treatment,” starring Gabriel Byrne and Dianne Wiest, for a second season. The half-hour psychotherapy drama shows psychoanalyst Paul Weston (Gabriel Byrne) as he treats patients – as well as his treatment by his own therapist, Gina Toll (Dianne Wiest).

The second season of “In Treatment” will move production from Los Angeles to New York and begin airing on HBO in fall 2009.
