The Witchblade TV series, which provided the TNT network with a major ratings boost last summer, is back in production and on track for a full 13-episode season starting on June 16.  Witchblade, which is based on a comic book published by Top Cow under the Image banner, had been on a brief hiatus, which occurred when the series' sultry, husky-voiced star, Yancy Butler, checked into rehab (see 'Witchblade Series On Hiatus').  Reports from the set indicate that Butler was back in action and filming again on June 10.
