William Sadler

An upcoming two episode arc of NBC's Chase will introduce viewers to the fugitive father of lead character, Deputy U.S. Marshal Annie Frost (Kelli Giddish). It was the search for her father that originally kicked off Annie's lifelong "chase."

Cast in the role of William Frost is character actor William Sadler, who was seen earlier this season in the premiere episode of CBS's Hawaii Five-0 as the father of Steve McGarrett (Alex O'Loughlin). That character didn't fare so well, and Annie's dad could also wind up dead if she doesn't act fast.

In the first of the two episodes, airing March 2, William's former associates start turning up dead. Annie must then make a desperate bid to track daddy down. But who will get there first? The daughter looking for resolution, or a psychopathic killer hell bent on revenge?

William previously played recurring roles on Roswell, Wonderfalls and HBO's The Pacific.

Chase returns this Wednesday (1/19) with new episodes in its new timeslot at 9/8c.
