“How many times have I told you - never fly straight and level for more than 30 seconds in a combat area!” 

The immortal lines from the Battle of Britain sum up the frantic scramble for the survival of Britain in the long, hot days of the summer of 1940. 

The film, despite its age, remains a classic and deserves to be watched time and again. 

Michael Caine, Laurence Olivier, Kenneth More, Ian McShane and more make up the stellar cast, ably assisted by a stunning array of Spitfires, Hurricanes, Messerschmitt 109s and Heinkel 111s.
