British babe Keira Knightley made her Broadway debut on October 1 and Broadway.com was on hand to witness it. The Oscar nominee took the stage with her Thérèse Raquin co-stars Gabriel Ebert, Judith Light, Matt Ryan and David Patrick Kelly at Studio 54. Knightley plays the title role in the drama about an unhappily married woman who does some dastardly deeds with her lover. (Did your eyes just widen as you scrambled to the get tickets link? Thought so.) Bravo to Keira and co. The show officially opens on October 29.
