This is Alfie (Tom Edden), not the star but definitely my favorite character in “One Man, Two Guvnors,” Richard Bean’s adaptation of Carlo Goldoni’s classic “The Servant of Two Masters.”

London’s National Theatre presents the play in high-definition at several local movie theaters as part of its NTLive series.
