Robert Boardman, who was originally cast as Francois-Marie Voltaire in the world-premiere play, has "left the production due to artistic differences," according to a press statement. Emilie's Voltaire had been scheduled to begin previews Off-Broadway Jan. 10 but delayed performances until Jan. 15. No reason was provided for the initial delay.

With the latest news of Boardman's replacement, Emilie's Voltaire has now announced that its official opening night of Jan. 22 has been rescheduled to Jan. 30 at the Samuel Beckett Theatre. Under the direction of Kevin Confoy, performances will continue through Feb. 7 as originally announced.

Medeiros, a veteran of "Law & Order," joins original cast member Amy Lynn Stewart in what is billed as "the true account of the volcanic, law-breaking, sexually-driven, intellectually-fuelled, sixteen-year love affair between Francois-Marie Voltaire and Emilie, Marquise du Chatelet," according to press notes. "He was a philosopher. An upstart poet. A free thinker. A blasphemer. A worshipper of Venus. Corrupter of morals. A playwright. He is on fire at the peak of his powers both intellectual and financial. She is arguably the most beautiful woman in France suffering the most tedious marriage in Europe and soon to emerge as one of the most profound physicists in the world. It is New Year's Eve 1733. The bells of Notre Dame are ringing eleven. The rest is history."

Emilie's Voltaire has designs by Jito Lee (scenic design), Jake DeGroot (lighting design), Carol Pelletier (costume design) and Geoffrey Roecker (sound design).
