Andrew Garfield, 22, won the Milton Shulman Award for outstanding newcomer for performances in Beautiful Thing, The Overwhelming and Burn/ Chatroom/Citizenship. LA-born Garfield was presented with the award by Eve Best. Previous winners include Rachel Weisz and Jake Gyllenhaal. The Charles Wintour Award for most promising playwright was won by Nina Raine, 31, for her drama Rabbit, which wowed West End audiences at the Trafalgar Studios after its transfer from the Old Red Lion. Kathy Burke presented the award to Raine.
The prize also comes with a cheque for £30,000, jointly donated by Lord Rothermere and former Evening Standard editor Charles Wintour's daughter Anna Wintour.
Raine said: "Last year I earned £9,000. It was an excellent year. When I heard I had won this award I was living with my uncle and aunt in the attic. When I got the news I stood up in shock, luckily in the one place you can do that without bashing your head. This award will truly be life changing."
Evening Standard editor Veronica Wadley flew the banner for West End plays, which have come under increasing threat from big-budget musicals. She said: "I am standing in the spotlight to lead the protest against the excess of musicals in the West End."
She added: "The great challenge to all of us is to encourage plays like Tom Stoppard's Rock'n'Roll and Peter Morgan's Frost/Nixon, one of the most thrilling pieces of theatre I have seen in years. Both of them attracted huge excitement, comments and audience."
The ceremony was hosted by Lady Rothermere, wife of Lord Rothermere, chairman of Daily Mail and General Trust, owner of the Evening Standard.
Guests included Kim Cattrall, Damian Lewis, Iain Glen, Jodhi May, Jane Asher, Brian Cox, Sir Peter Hall, Dominic West, Alice Eve, Sir John Mortimer, Sonia Friedman and Patrick Stewart.
