Reginald Beck was a British film editor with forty-nine credits. He was born in Russia, but his family emigrated to Britain while still a child. He began working in the film industry in 1927 when he joined Gainsborough Pictures before going on to work on quota quickies at Wembley Studios. He later worked with a number of directors including Carol Reed, David Lean, Laurence Olivier and Joseph Losey. In his obituary, Anthony Sloman wrote of the seventeen films that Beck edited with director Losey, "Their professional and personal relationship was regarded as one of the great screen partnerships".
Beck worked with Laurence Olivier on Henry V and on Hamlet. Sloman writes, "above all, it is for his immense contributions to Henry V and Hamlet that the British film industry is forever in his debt."
