The third most successful movie at the American box-office for 1962 after El día más largo (1962) and Lawrence de Arabia (1962).
Hayley Mills made this movie about shipwrecked castaways two years after her father, Sir John Mills, starred in Los robinsones de los mares del Sur (1960) also made by Walt Disney about shipwrecked castaways.
Wilfrid Hyde-White replaced Charles Laughton as Lord Glenarvan. Laughton was originally announced as the character, but Laughton's illness and subsequent death forced Producer Walt Disney to replace him with Hyde-White.
One day on-set Hayley Mills almost accidentally burned down her dressing room. After filming a scene in which her clothes became soaked, without thinking, she put a pair of wet trousers on top of an electric heater before leaving the room. If it had not been for a crew member noticing the smoke which began to billow out of the room, Mills' dressing room, and possibly part of the set, could have been destroyed.
