NEW YORK (AP) -- ABC says Dominic Monaghan (MAHN'-uh-han) is joining the cast of its upcoming sci-fi drama, "FlashForward."

Monaghan is best known as the doomed rock star Charlie from ABC's "Lost."

He will face new challenges on "FlashForward," when the world's population simultaneously suffers a blackout, then recovers with visions of what may, or may not, be waiting in the future.

Previously announced stars of "FlashForward" include Courtney B. Vance and Sonya Walger.

It premieres Sept. 24.
