Mustn't Grumble. The Blue Lamp is directed by Basil Dearden and written by T.E.B. Clarke. It stars Jack Warner, Jimmy Hanley, Dirk Bogarde, Robert Flemyng and Peggy Evans. Music is by Ernest Irving and cinematography by Gordon Dines. Andy Mitchell is a new recruit to the London police force, old hand George Dixon takes him under his wing and shows him the ropes. When Dixon is gunned down by a hot headed crook, Mitchell, the force, and the close knit community, all rally round to catch the villain. What chiefly makes The Blue Lamp a fine watch is being able to witness the good old days...
