Arrested Development alum Will Arnett has joined NBC's untitled Emily Spivey comedy pilot, starring opposite Christina Applegate and Maya Rudolph.

The project, written by former Saturday Night Live scribe Emily Spivey, is described as an irreverent look at parenthood through the point of view of an acerbic working mother (Christina Applegate) -- who never thought she'd be a mom -- along with her stay-at-home husband (Will Arnett) and opinionated parents.
