In Treatment will return for a second season some time in 2009.

While we don't have an exact premiere date yet, we have learned of a few new patients Gabriel Byrne's Paul Weston will be helping:

• Hope Davis will portray a high-powered malpractice lawyer and former patient of Weston's who blames him for being single and childless;
• John Mahoney will portray a CEO who feels that his life is getting away from him. 

Sources also now confirm that In Treatment has booked Russell Hornsby as one of Dr. Weston' regular patients. The actor, pictured, will play a divorced man with a 12-year-old son.
