Jennifer Jason Leigh will play the estranged older sister of Nancy Botwin (Mary-Louise Parker) on at least two upcoming episodes of Showtime’s Weeds, according to The Hollywood Reporter. The fifth season of the show, which follows the misadventures of a suburban housewife-turned-drug dealer (Parker), will debut in June. Leigh will next be seen on the big screen opposite Ben Stiller in 2010’s Greenberg, a drama written and directed by Leigh’s husband, Noah Baumbach (Margot at the Wedding).
