  • Merchant of Venice

    Antonio was played by Feargal Mostyn-Williams. Mostyn-Williams did a superb job of conveying a tortured soul and looking particularly pale and petrified while facing the potential extraction of a pound of flesh. His interaction with Bassanio was entirely believable and heartfelt

    Cardiff Shakespeare
  • Merchant of Venice

    Feargal Mostyn-Williams, called up at the last moment for his first principal role with a major company, performed heroically as Antonio. He has a sweet voice with a lovely upper register, and acted like a veteran
