With just two episodes left of the first season of Smash, Bombshell performs for an audience for the first time, but Uma Thurman’s Rebecca Duvall may have gotten poisoned. Check out a promo and sneak peek for “Preview” released after Monday’s episode of Smash below.

Episode synopsis: “Bombshell” faces its first audience just as a major crisis hits Rebecca Duvall (special guest star Uma Thurman). The team of Tom (Christian Borle) and Julia (Debra Messing) scramble to fix the show when the first preview falls short, and Frank (Brian D’Arcy James) must adjust to the unwelcome return of Michael Swift (Will Chase) to his life. Dev (Raza Jaffrey) seeks reconciliation with Karen (Katharine McPhee), but explosive information about Ivy (Megan Hilty) lurks just beneath the surface. Jack Davenport and Anjelica Huston also star.
