Eion Bailey (“Once Upon a Time”), Katherine McNamara (“Arrow”) and Hamish Linklater (“Legion”) have all been added to the massive cast in “The Stand”, CBS All Access’ limited-series adaptation of Stephen King’s classic novel, reports Deadline.

The trio joins Alexander Skarsgard, James Marsden, Amber Heard, Odessa Young, Jovan Adepo, Owen Teague, Henry Zaga, Brad William Henke, Whoopi Goldberg, Daniel Sunjata and Nat Wolff in the drama, which is currently filming in Vancouver.

The Stand is King’s apocalyptic vision of a world decimated by plague and embroiled in an elemental struggle between good and evil. The fate of mankind rests on the frail shoulders of the 108-year-old Mother Abigail (Goldberg) and a handful of survivors. Their worst nightmares are embodied in a man with a lethal smile and unspeakable powers: Randall Flagg, the Dark Man (Skarsgård).

Bailey, pictured above, will play Teddy Weizak, a superflu survivor and member of the body crew, alongside Harold (Teague), in Boulder, CO. McNamara, below, is Julie Lawry, a small-town girl with a wild side who is one of Lloyd’s (Wolff) conquests in Las Vegas. Linklater is set as Dr. Ellis, a military colonel and infectious-disease specialist who dreams of being the hero who stops the superflu.

The series is written by Josh Boone and Ben Cavell.
