HBO is entering "Treatment," and it's going to be there for a while.

The pay-cable network has picked up the half-hour drama "In Treatment," which stars Gabriel Byrne as a therapist who's highly competent with his own patients but an utter mess when he sees a shrink. Instead of a typical 13-episode commitment, though, HBO has ordered 40 episodes, according to The Hollywood Reporter.

That's on top of the five shows the network had already greenlit and treated as an extended pilot, bringing the total to 45.

Additionally, HBO has ordered the hour-long comedy "12 Miles of Bad Road," which stars Lily Tomlin as the head of a wealthy Texas family. Its episode order hasn't been nailed down yet, the HR says.

"In Treatment," based on an Israeli series of the same name, also stars Dianne Wiest ("Law & Order," "Bullets Over Broadway"), Blair Underwood ("Old Christine"), Embeth Davidtz ("Bridget Jones's Diary") and Melissa George ("Alias"). The Israeli show's creator, Hagai Levi, is executive producing with Mark Wahlberg ("Entourage"), Stephen Levinson and Rodrigo Garcia ("Six Feet Under"), who will serve as showrunner.

"Bad Road" comes from Linda Bloodworth-Thomason and Harry Thomason ("Designing Women"). Its ensemble cast includes Gary Cole ("The West Wing," "Talladega Nights"), Kim Dickens ("Deadwood"), Katherine LaNasa ("Justice"), Mary Kay Place ("Big Love") and Ivana Milicevic ("Love Monkey").
