"Glee" is giving former "Saturday Night Live" star Molly Shannon some primetime exposure.
The Fox series has cast Shannon in a guest role as a nemesis to Jane Lynch’s Sue Sylvester character, a rep for 20th Century Fox TV confirmed to TheWrap.
Shannon will play Brenda Castle, an astronomy teacher and badminton coach at McKinley High School with substance abuse problems.
The guest stint could turn into a recurring role.
Shannon’s last big TV gig was as co-lead in NBC’s failed remake of the Australian sitcom "Kath and Kim."
