Neal Baer cast an ER veteran in a key role: Anthony Edwards will tackle the part of Mars Harper, a.k.a.
Julie White of the Transformers franchise will play Kirkman’s campaign manager, and her character may not get along so well with Edwards’ character.
It’s too soon to say if Designated Survivor will have characters showing more skin (as happened with Lucifer) or dropping F-bombs, but the possibility for darker and edgier characters is very much there.
