We’re back this month with Cortney’s TV Digest, everything you need to know about the latest and greatest shows on the tube. This month we’ve got some interesting new shows to tell you about from a bunch of your favorite networks, as well as the resurrection of one show we worried we’d never see again.

Parenthood – NBC

Based on the 1989 film of the same name, this new show is produced by movie and tv genius Ron Howard. The show follows the parenting experience of the Bravemen family: single mom Sarah (Lauren Graham), her brother Adam (Peter Krause) and wife Christina (Monica Potter) whose son is diagnosed with Asperger’s Syndrome, and their headstrong father (Craig T. Nelson). Parenthood premiers March 2nd at 10 PM on NBC.

Southland – TNT

Back in 2009, NBC premiered their new, gritty cop drama, Southland. The show centered around Los Angeles and the members of the LAPD, including The OC’s Ben Mackenzie as rookie Officer Ben Sherman. Shortly before the beginning of its second season, NBC suddenly canceled Southland. It was doubtful whether we’d ever see the six episodes scheduled to air, but TNT swooped in and bought them, effectively saving the show from certain doom. The previous season began airing in January and season 2 starts on March 2nd.

Parenthood, which is based loosely on the Steve Martin comedies from a few years ago, is a new the new series from Brian Grazer and Ron Howard covering the ins and out and trials and tribulations of modern parenting. We’ve brought you some info on the show previously and now we’ve got even more info to bring you this time around about the show, its cast and creators.

In this series of nine video clips videos you get to know the main characters of the upcoming comedy. These clips showcase some footage from the series itself and interviews with the actors as they talk about their roles on the show. And, as a bonus, creators Ron Howard and Brian Grazer discuss the inspiration for the show which came from their real life parenting experiences.

With a cast that includes Peter Krause, Monica Potter, Lauren Graham, Erika Christensen, Dax Shepherd, Bonnie Bedelia and Craig T. Nelson, the show looks to have all the requisite acting power necessary. Combine that with creators/producers Ron Howard and Brian Grazer and it seems to have a great mixture for success. Let’s hope the show lives up to its potential.

Catch the premiere of Parenthood on Tuesday, March 2 at 10/9C on NBC. Check out all the videos after the break.
