Saturday Night Live vet Molly Shannon will join the cast of Glee as a "busty 45-year-old new astronomy teacher and badminton coach"/"Sue Sylvester rival" Brenda Castle. I'm bracing myself for trenchant barbs about where Brenda can shove a shuttlecock already. Now, what about the remaining two members of SNL's late '90s lady troika? Sue Sylvester could easily seek the advice of a life coach played by Cheri Oteri, of course, but inserting herself within the drama of Ana Gasteyer's last film, Dare, is tricky. [EW]
