Paul Campbell, who on Battlestar Galactica played President Roslin's loyal (and ill-fated) aide, Billy, has been added to the cast of NBC's Knight Rider, which premieres as a series this fall.

Campbell will play the head research tech at Knight Industries, says the Reporter, which means he and perhaps only he can explain why KITT went from being all sleek to brick-like. - Matt Mitovich
