Wonderfully energetic production. Ronstadt is pretty lame, but the rest of the cast, Kline in particular, are great.
Leonard Maltin/Plot synopsis:
Joseph Papp's hit stage revival of the Gilbert and Sullivan perennial is transferred to film with the original cast (plus Lansbury) and director--who decided to make no bones about its theatricality! Not for G&S purists, perhaps, but fun. Splendid production design by Elliot Scott. Panavision.
