Now add ''The Virgin Queen" to the list of PBS's Sunday night gems, and see it as evidence that ''Masterpiece Theatre" still has a distinguished purpose. The life of Elizabeth I has been filmed many times before, but director Coky Giedroyc and writer Paula Milne both bring a distinctive operatic sweep to their story of the queen who resisted the pressure to marry. ''The Virgin Queen" takes an emotionally charged approach, with a nakedly expressive performance by Anne-Marie Duff as Elizabeth and with the sort of rhythmically edited sequences and heightened soundtrack you might expect in a Baz Luhrmann movie. There's nothing stiff or musty about the two-part miniseries, which premieres tomorrow night at 9 on Channel 2 and concludes next Sunday.
Duff's Elizabeth is brattier and more physically forward than those actresses who've preceded her in the role, particularly Glenda Jackson, who created an eerily complex and shrewd queen in 1971's ''Elizabeth R." She looks a little like Holly Hunter in ''The Piano," with impassioned body language and the stark face of a silent-movie actress. As a young woman, freed from the Tower after her half-sister, Queen ''Bloody" Mary, dies, Duff's Elizabeth is a creature of childlike joy. She's in love with courtier Robert Dudley (Tom Hardy), and the fact that he's married doesn't stop her from openly flirting with him in front of her court. She relishes the giggly friendship of her two ladies in waiting (one of whom will later betray her). But then she also has childlike fits of temper that leave her screaming aloud to herself in the cavernous castle halls. She's fully aware of her royal blood.
