Laurence Naismith was an English actor. He made numerous film and television appearances, including starring roles in the musical films Scrooge (1970) and the children's ghost film The Amazing Mr. Blunden (1972). He also had memorable roles as Captain Edward Smith of the RMS Titanic in A Night to Remember (1958), the First Sea Lord in Sink the Bismarck! (1960), and Argus in Jason and the Argonauts (1963).

Sink the Bismarck! is a 1960 black-and-white CinemaScope British war film based on the 1959 book The Last Nine Days of the Bismarck by C. S. Forester. It stars Kenneth More and Dana Wynter and was directed by Lewis Gilbert. To date, it is the only film made that deals directly with the operations, chase and sinking of the battleship Bismarck by the Royal Navy during the Second World War. Although war films were common in the 1960s, Sink the Bismarck! was seen as something of an anomaly, with much of its time devoted to the "unsung back-room planners as much as on the combatants themselves". Its historical accuracy, in particular, met with much praise despite a number of inconsistencies.
