Peter Dinklage, one of the ensemble cast members of the short-lived, but interesting Threshold series, obviously holds no ill-will toward CBS as he is returning to the network to star in another scifi drama called “Ultra.”

Based on the Ultra comic book serial, Lena Headey stars as the single urban-girl superhero and Dinklage plays The Scientist.

Dinklage gained notoriety in the critically acclaimed 2003 film “The Station Agent.” And while he was an actor who worked fairly steady before, after that film he has seen some real meaty roles come his way. In fact, in 2006 alone he has six feature films on the docket at various stages of development.
