Billions type TV Show network Showtime

Billions is buying into Mary-Louise Parker.

The Weeds and West Wing alum is on board to guest star in the sophomore season of Showtime’s financial drama, EW has learned. Appearing in a single episode, Parker will play a brilliant strategist named George Minchak.

Set in the cutthroat world of Wall Street wheeling and dealing, Billions centers on the rivalry between cocky hedge fund titan Bobby “Axe” Axelrod (Damian Lewis) and dogged U.S. Attorney Chuck Rhoades (Paul Giamatti). The cast also includes Maggie Siff as Chuck’s estranged wife, Wendy, and Malin Akerman as Axe’s street-smart better half, Lara.

Other guest stars lined up for season 2 include Rob Morrow, Dan Soder, Kelly AuCoin, James Wolk, Christopher Denham, Glenn Fleshler, and Eric Bogosian.

Billions returns Sunday, Feb. 19, at 10 p.m. ET on Showtime.
