The New Girl cast is full of hugely talented actors bringing its quirky, lovable characters to life. The series revolves around Jess Day, a bubbly teacher who moves into a loft in Los Angeles with three wacky roommates after catching her boyfriend cheating on her. Created by Elizabeth Meriwether, New Girl ran for seven seasons and was a hit with both critics and audiences. The New Girl cast was given the freedom to improvise lines, and the spontaneity of the ad-libbed dialogue went a long way toward making the characters feel real and catching the attention of a mainstream audience.
