Much of A.R.T.'s cast returns from participating in a workshop of Pippin last summer. The new production of the Stephen Schwartz-Roger O. Hirson musical will incorporate circus choreography and acrobatics by Gypsy Snider of the Montreal-based circus company Les 7 doigts de la main (7 Fingers). Thomas will lead the cast as Pippin, with Miller (Sister Act, Hair) as the Leading Player, Martin (My Favorite Year) as Berthe, Mann (Les Miserables, The Scarlet Pimpernel) as King Charles, d'Amboise (Chicago, Carrie) as Fastrada, Erik Altemus (The Fantasticks) as Lewis, Andrew Cekala (Marie Antoinette) as Theo and Rachel Bay Jones (Women on the Verge..., Hair) as Catherine.
