Molly Shannon is set to play Kath in NBC's comedy pilot Kath and Kim, according to The Hollywood Reporter.

Kath and Kim centers on a dysfunctional mother-daughter relationship. Shannon will play the mother; the role of the daughter is yet to be cast.

The trade paper says that casting the title characters has been considered crucial to the success of the show. When the project was first picked up to pilot by NBC in January, it was pushed to summer because of difficulties casting the leads.
