The actor has made a slew of guest appearances in TV shows over the years, plus appeared in movies such as "Traffic," "Capote," "Crank: High Voltage," in addition to "Star Trek," where he played a Romulan villain.

NBC has kept details about "The Event" under wraps, though the network plans to follow in the footsteps of ABC's "Lost" and screen the entire pilot at Comic-Con next week. "The Event" will debut on NBC on Monday, Sept. 20.

Collins is repped by Kim Callahan at Affirmative Entertainment and attorney David Krintzman.
