Director Robert Hastie brings his bold and inventive production of Hamlet for the National Theatre of Great Britain to the Brooklyn Academy of Music (BAM), a fitting first outing in the new partnership between these venerable institutions—BAM first performed Hamlet in 1861, and it was the National’s inaugural production in 1963. Hiran Abeysekera portrays the moody Danish prince as sweet, neurotic, and impish, drawing out the comedy in the play without sacrificing its complexity and tragic weight. Hastie and Abeysekera seize on Hamlet’s theatricality and theatrical self-awareness, taking it to a new and provocative level.
