Showtime has announced that "Nurse Jackie" and "United States of Tara" — featuring stage veterans Edie Falco and Toni Collette, respectively — will premiere their sophomore seasons back-to-back March 22.

The cable network currently presents encore runs of the first seasons of both half-hour shows in the time slots they will air the second season: Mondays at 9 PM and 9:30 PM (Times are ET/PT.)

Falco ('night, Mother and Frankie and Johnny in the Clair de Lune) stars in "Nurse Jackie" as the title medical professional whose own life could use some attention. Fellow stage stars Eve Best (A Moon for the Misbegotten, The Homecoming) and Anna Deavere Smith (Twilight: Los Angeles, 1992 and Let Me Down Easy) are also series regulars.

In "United States of Tara," Colette (The Wild Party) plays the title character — or rather characters — who suffers from Dissociative Identity Disorder, allowing the actress to bite into multiple personalities. Rosemarie DeWitt — seen Off-Broadway in Danny and the Deep Blue Sea, Small Tragedy and the upcoming Family Week — co-stars as her sister.
