The vampire-filled series created by Alan Ball ("Six Feet Under", All That I Will Ever Be) and based on Charlaine Harris' "Southern Vampire" book series centers on a young waitress, Sookie Stackhouse (played by Anna Paquin), who can hear people's thoughts.
Woodard (Drowning Crow) will reportedly appear as mother of cook Lafayette Reynolds (Nelsan Ellis). Frain (The Homecoming) will join the cast as a vampire who connects with Sookie's friend Tara (Rutina Wesley). And Smith-Cameron (The Starry Messenger) will take on the role of mother to Sookie's shape-shifting boss Sam Merlotte (Sam Trammell).
