News from TV Guide:
Joss Whedon is letting his obsession with Battlestar Galactica get the best of him — and I couldn't be happier about it!
Whedon has tapped Galactica stud Tahmoh Penikett (aka Helo) to play Eliza Dushku's "twisted romantic foil" in [his new series] DOLLHOUSE, a spokesperson for Twentieth Television confirms.
Penikett's character, Paul Smith (originally named Paul Ballard), is described as an FBI agent who becomes obsessed with both the urban myth that is Dollhouse and its most recognizable inhabitant, Echo (Dushku).
Here is another description of the character, from E!Online:
Tahmoh Penikett as Paul Smith: 30s, good looks hardened by a cynical distaste for most of humanity. An FBI field agent, he's been chasing the urban myth of the Dollhouse long enough to have lost any shot at promotion. Becomes obsessed with and a twisted romantic foil for Echo (Eliza Dushku).
Whedon's DOLLHOUSE has a 7-episode order from Fox; no word yet on how many of these eps Tahmoh will be featured in.
