Helen Mirren was crowned best actress at Britain's top theatre awards on Sunday for reprising her Oscar-winning portrayal of the queen, while a stage version of a novel about a boy with autism was on track to be the top winner of the Olivier awards.
Mirren, 67, has won stellar reviews for starring in "The Audience," Peter Morgan's play about the private weekly meetings between Queen Elizabeth and the 12 British prime ministers during the six decades of her reign.
Mirren is no stranger to royalty having won an Academy award for the same role in the 2006 film "The Queen".
The actress said the queen certainly deserved an Olivier award after receiving one of Britain's most prestigious entertainment honors, a BAFTA, earlier this month for her support for the film and television industry.
"I think she deserves one for the most committed and consistent performance of the 20th century and probably the 21st century," said Mirren on accepting the award from Harry Potter actor Daniel Radcliffe.
Her co-star, Richard McCabe, won the award for best supporting actor for playing the prime minister Howard Wilson.
