She was pitted against the likes of Gillian Anderson, Imelda Staunton and Juliet Stevenson for the title. Also, Weisz's co-star Ruth Wilson won Best Actress in a Supporting Role for her outstanding performance as Stella in the play by Tennessee Williams.
Meanwhile, Mark Rylance took home the best actor for his role in 'Jerusalem'. American playwright Katori Hall bagged the Best New Play award for her play 'The Mountaintop'. It tells the story of Martin Luther King the night before his assassination. She is the first black female playwright to win the award.
"The Olivier Awards reflect a year of outstanding creativity and production excellence which brought the public rushing to the theatre taking box office and attendance records to an all-time high," the Telegraph quoted Nica Burns, President of the Society of London Theatre, as saying. She added: "The London theatre is a shining light in the continuing recessionary gloom - something we can all be proud of."
