Red Flag No. 74 that Cane is toast. Polly Walker, who in addition to a run on HBO's Rome appeared on CBS' ill-fated drama series, is the latest to join the cast of Sci Fi Channel's Battlestar Galactica prequel.

On Caprica, which will premiere as a two-hour movie/backdoor series pilot, Walker will play Sister Clarice Willow, an eloquent (if duplicitous) high priestess and headmistress of a private religious school. - MWM
