Jessy Schram and Kevin Dunn have boarded Fox's action drama "Unstoppable," joining Denzel Washington, Chris Pine and Rosario Dawson, who also recently was cast.

Tony Scott is directing the Mark Bomback-scripted film about the desperate efforts of a veteran engineer and novice conductor to stop a train laden with toxic cargo speeding out of control toward a nearby city.

Schram will play the estranged wife of Pine's character. Dawson will take on the role of a train dispatcher helping the men via radio, and Dunn will play her boss.

Julie Yorn is producing with Scott and Mimi Rogers; Chris Ciaffa is an executive producer.

The project lost some momentum two months ago when budget concerns knocked it off track, but it again is scheduled to begin production in the fall in Pittsburgh.

Schram, repped by UTA and Kritzer Levine Wilkins Griffin Entertainment, had recurring roles on NBC's "Life" and the CW's "Veronica Mars." She next appears in the untitled TNT sci-fi pilot from executive producer Steven Spielberg.

Dunn, repped by Gersh and Lighthouse Entertainment, most recently appeared in "Transformers: Revenge of the Fallen" and "Vicky Cristina Barcelona." He was a regular on ABC's "Samantha Who?"
