Cusack is Janney’s Shameless replacement

Janney starred in the Showtime series pilot as a mum coping with her sexually active daughter, but she quit the production to take a lighter role in upcoming TV comedy Mr. Sunshine.

And now Cusack has signed on to fill the spot, just weeks before production is set to begin, reports Variety.

Cusack will star with Emmy Rossum and William H. Macy in the new series, scheduled to broadcast on 9 January (11).
