Wiig and Osment also appeared in the first installment of the Spoils franchise, The Spoils of Babylon, which aired on IFC last year and earned Wiig an Emmy nomination for Outstanding Lead Actress in a Miniseries.
Set in 1962 during the height of the Los Angeles jazz scene, the second installment is in production now and will debut this summer on the cable television network.
Other new cast additions to The Spoils Before Dying include Kate McKinnon, Tim Meadows, Chris Parnell, Emily Ratajkowski, Andrew Daly, Chris Mulkey, Chin Han, Jack Kilmer, Patty Guggenheim and Bérénice Marlohe.
"We couldn't have asked for a more talented cast to usher in the sophomore season of this miniseries," Jennifer Caserta, IFC's president, said in a statement Tuesday. "We're also thrilled to have so many of last year's Spoils cast members returning for Jonrosh's latest adaption, particularly Kristen Wiig who received an Emmy nomination for her hilariously epic performance."
Michael Kenneth Williams was previously announced as Rock Banyon, "a struggling jazz pianist at the center of this pulp-noir murder mystery," while Will Ferrell reprises his role of Eric Jonrosh, "the literary auteur-turned-director who opens and closes each spellbinding episode of his latest lurid television adaption," a synopsis said.
