Melissa McCarthy is coming back to primetime TV for the upcoming comedy, Nobodies, and ET sat down with her -- along with the rest of the cast -- to find out what fans can expect.

Hugh Davidson (Robot Chicken), Larry Dorf (Mike Tyson Mysteries) and Rachel Ramras (The Looney Tunes Show) write and star in the series as three comedians determined to get their famous friend (McCarthy) attached to a feature script they have developed so that they, too, can rise to fame. McCarthy and her husband, Ben Falcone, serve as executive producers on the show alongside MADtv veteran Michael McDonald, who serves as showrunner. McCarthy and Falcone also make onscreen appearances.

The series very loosely mirrors their real lives as McCarthy and Falcone became friends with Davidson, Dorf, Ramras and McDonald at The Groundlings sketch and improvisation comedy theatre and school in Los Angeles.

"Ben and I play horrific versions of ourselves," McCarthy admitted.

And they have even more of their famous Groundlings pals geared up for guest appearances.

"Kristen Wiig comes in," McCarthy said, "Maya Rudolph, Allison Janney comes in, and Jason Bateman is in the pilot ... Kristen Bell."

Oscar winners Jim Rash and Nat Faxon also appear in the pilot episode.

"All of our famous Groundlings friends -- and there are many -- have all agreed to be on the show and play heightened versions of themselves -- not always in the most flattering light -- because it really truly is a family," said Ramras. "These are the closest friends that we've had for so many years."

With so much talent onboard, the series has already been picked up for a second season before the first episode has even aired. The series premiere is set for March 29 on TV Land.
