Showtime’s upcoming comedy, “Black Monday,” has added a few new names to its list of guest stars.

Bruce Dern, “The Big Bang Theory” star Melissa Rauch and “Saturday Night Live” alum Horatio Sanz have signed on to appear in the 10-episode comedy from “Happy Endings” creator David Caspe.

The 1980-set series centers on the worst stock market crash in the history of Wall Street, with Don Cheadle, Andrew Rannells and Regina Hall set to star.

Dern will play Rod, a legendary trader; Sanz will play Wayne, a Wall Street wild man who works at Mo’s (Cheadle) Jammer Group; and Rauch will play Shira, the loving wife of trader Keith (Paul Scheer).

Other guest stars include Julie Hagerty as Jackie Georgina, the matriarch of a designer denim empire. Vanessa Bell Calloway and Tim Russ as Dawn’s (Hall) artist mother Ruth and professor father Walter. “Book of Mormon” star Jason Michael Snow will play Mike, a Broadway actor, and previously announced guest star Kadeem Hardison will play Spencer, Dawn’s husband.

In addition to starring, Cheadle will serve as executive producer alongside Caspe, Seth Rogen and Evan Goldberg, who will direct the pilot. Paul Scheer, Yassir Lester, Michael James Scott and Eugene Cordero will also star, with “Happy Endings” alum Casey Wilson, Ken Marino and Kurt Braunohler to recur.

“Black Monday” is a co-production by Showtime and Sony Pictures Television, where Caspe’s Shark vs. Bear banner has an overall deal. It is slated to premiere in January.
