Michael Rooker (Merle Dixon) is Mike Harper. He previously voiced himself in the Black Ops Zombies map "Call Of The Dead."
Jennifer Hale makes a short appearance as Anderson, a pilot who provides close air support in "Cordis Die". For bonus points, her character's first appearance is backed by music absurdly similar to the de facto Mass Effect 2 (where she voiced female Commander Shepard) main theme, 'Suicide Mission' — Jack Wall wrote the soundtracks for both games.
Ayana Taketatsu makes a short appearance as Anderson, a pilot who provides close air support in "Cordis Die".note And being her first role doing a dub of a foreign media, if we include her role as Victoria in the Japanese version of Hitman: Absolution.
The Other Darrin: Hudson is voiced by Michael Keaton instead of Ed Harris. It's very noticeable as the two sound nothing like each other. In Declassified Hudson is at least voiced by a voice actor trying to pull off a reasonable Ed Harris impersonation.
