For the first time ACT (A Contemporary Theatre) of Connecticut in Ridgefield has launched its inaugural musical — Mamma Mia! A full equity theater, this cast is truly as professional as they come. Directed by the theater’s artistic director Daniel C. Levine, it’s not surprising that this show is flawless. After all, Levine appeared on Broadway as well as in the Broadway National Tour of this show. He knows this musical inside out and it shows.
