Marc Menard — whose stint on Lost as Rousseau’s fellow French scientist Montand ended with him losing a limb to El Monster de Smoke — is joining the CW soap in the potentially recurring role of Father Cavalia, a priest from Monaco with ties to Blair’s fiancé, Prince Louis.
There’s been speculation that the comely pontiff heads to the Upper East Side to preside over the couple’s wedding ceremony. If true, he may encounter some resistance from Louis’ meddling sister, played by French actress Roxane Mesquida.
Menard’s casting comes two days after TVLine broke the news that Elizabeth Hurley is UES-bound.
