Emmy Award winner and Tony nominee Allison Janney (9 to 5, "The West Wing") will appear in the show's pilot as a character who had a recurring role on the 2004 British series on which the show is based.
The series stars Macy (Speed-the-Plow, Oleanna, "Fargo") as a working-class, hard-drinking father of six children. Rossum ("The Phantom of the Opera") will play his oldest child.
The show will be executive produced by John Wells and Paul Abbott.
