This film will be of great interest to WW2 Aviation enthusiasts as it features several authentic Italian Savoia - Marchetti S.M. 79 three - motor bombers. These aircraft were provided by the Lebanese Air Force which was the last operator of the type.

I would make an educated guess that this film was shot on Cyprus as there is an abundance of British Army trucks and armoured cars modified and painted to resemble German vehicles. A Bristol Beaufighter aircraft can also be briefly glimpsed during the airfield attack sequence.

The special effects ,such as model aircraft being blown up, are not up to modern standards but they are no worse than other 1950s war movies such as "The Dambusters".

"They Who Dare", which Lewis Milestone directed in 1953, comes across as a kind of preamble for "The Guns of Navarone" and was handsomely shot on location. It deals with the exploits of a small group of British and Greek soldiers tasked with blowing up German air bases on Rhodes but is rather lacking in action; most of the time is spent on the journey to the targets thought when the fighting does start it is lively enough. This is Dirk Bogarde in handsome, dashing leading man mode rather than Bogarde the actor he was ultimately to become and others in the cast include Denholm Elliot and Akim Tamiroff, though they are both wasted. It's hardly comparable to Milestone's other war movies but it's far from being a right-off either.
