Moore (MADtv, 90210) has been cast as a Texas housewife with special abilities, a recurring role. She will film her part on the HBO series while HawthoRNe, the TNT drama in which she is a regular, is on hiatus.
Both Hopkins (Lost, Skyline) and Butler (The Good Wife) will appear in multi-episode arcs. Hopkins will play Claude, brother to Claudine, the queen of the fairies. Butler will play Emory, a conservative shapeshifter.
