Luke Treadaway, the British actor often dubbed a 'rising star' in the industry, won best actor at a glitzy Olivier Awards ceremony in London on Sunday (April 28, 2013). The National Theatre's adaptation of Mark Haddon's 2003 murder mystery The Curious Incident of the Dog In The Night-Time won seven awards in total, with Treadaway fending off stiff competition from Mark Rylance, James McAvoy and Rupert Everett to win best actor for his role as maths genius and Aspergers sufferer Christopher Boone, who sets out to solve the mystery of who killed his neighbour's dog.

"This is for everyone who worked on the show. I can't believe it.This is absolutely amazing," said Treadaway after accepting the award from Sex and the City star Kim Cattrall. His co-star Nicola Walker was named best supporting actress for her role as Christopher's guilt ridden mother, saying, "My agent told me to breathe if I won, and my husband told me not to swear...Every single day of rehearsals and every single performance was a prize, so this is completely overwhelming."

Elsewhere, Richard McCabe was named best supporting actor for his role as Harold Wilson in The Audience, while the play's lead Dame Helen Mirren won best actress for her role as The Queen. It is the fourth time Mirren has been honored for the same part.

This year's ceremony, held at the Royal Opera House at Covent Garden, was hosted by Sheridan Smith and Downton Abbey star Hugh Bonneville. Other recipients included Michael Ball and Imelda Staunton, named best actor and actress in a musical, for their respective roles in Sweeney Todd. The show also picked up best musical, fending off competition from A Chorus Line, Cabaret and Kiss Me Kate. "I'm delighted to accept this on behalf of all of us.This was one of those lucky productions that was so enjoyable to rehearse and entirely satisfying to do."

However, it was The Curious Incident of the Dog in the Night-Time that was the big winner. The show premiered at the National Theatre last year and has now transferred to the Apollo.
