Kenneth Branagh’s ambitious, full-length Hamlet lacks the streamlined gutsiness of his Henry V. One can also quibble with the flashbacks and cameos (Billy Crystal, Robin Williams). But he mostly pulls it off, capturing terrific performances (Derek Jacobi’s Claudius, Kate Winslet’s Ophelia), often in elaborate single takes that would make Vincente Minnelli swoon. EXTRAS In a commentary with Shakespeare scholar Russell Jackson, Branagh defends his flashbacks, says Williams did ”wonderfully well” as a courtier, and calls Crystal’s Gravedigger ”a treat.”
