Weeds is sweetening the pot in its third season.
Sources confirm that Matthew Modine is joining the cast for a 10-episode arc. He'll play a real-estate developer who's building a new community next to Agrestic. And in between bong hits, he'll be romancing both Mary-Louise Parker
and Elizabeth Perkins - although probably not at the same time. The show's called
Weeds, not
Nip/Tuck.
