Mandy Moore has signed on to star in ABC's single-camera comedy Us and Them, from 20th Television.

The family comedy explores the inherent conflict that exists between the families you grow up in and the ones we make as adults and is told through from the perspective of Annie (Mandy Moore) and Ben, a young, newlywed couple.

ABC has given a put-pilot commitment to the project, which comes from Marty Adelstein and Becky Clements' 21 Laps/Adelstein shingle. Bob Fisher will pen the project.
