Helen Mirren won her first Tony on Sunday (7 June) for her role as Queen Elizabeth II in The Audience, and the lesbian-coming of age story Fun Home nabbed the top acting prize for Michael Cerveris and best musical at the 69th Tony Awards.
Mirren adds her Tony award – Broadways highest honour – to an Emmy and an Oscar.
British import The Curious Incident Of The Dog In The Night-Time, about a teenage math wizard with Aspergers Syndrome who goes on an incredible journey, won five awards including best play, director and actor for its star, recent Juilliard School graduate Alex Sharp.
Sharp, in his Broadway debut, surpassed Hollywood star Bradley Cooper and veteran actor Bill Nighy for the best actor accolade.
Cerveris took home best actor in a musical, his second Tony, for playing the closeted homosexual father in Fun Home, which also scooped best director Tony for Sam Gold, as well as best book and best score.
After six nominations, Kelli OHara took home her first Tony for best actress in a musical as the governess in The King And I.
Past winners Kristin Chenoweth and Alan Cumming co-hosted the ceremony, which was broadcast live on CBS television and featured songs from top musicals.
The three-hour show capped a record-breaking season on Broadway in which audience numbers topped 13.1 million and ticket grosses rose to $1.36bn (£890,000).
