One of my female friends once told she hated "Memphis Belle but she liked this film. It is not hard to see why. It is more of a Barbara Cartland style romance than an action adventure movie.
One interesting point is that former RAF /USAAF airfield at Bovingdon was used for filming. It was previously used as the location for a number of air movies such as "633 Squadron","Mosquito Squadron" and "The War Lover". By the time "Hanover Street" started filming in 1978 it was disused and derelict so the aircraft were only filmed with very long lenses to avoid showing the background clearly.
The film suffers from too many historical and technical errors to be taken seriously by WW2 buffs. For example there is a discussion about "light " and "heavy flak" which makes it clear that writer/director Peter Hyams thinks these terms refer to the number of guns employed whereas in fact they refer to the calibre of the weapons. For example a target defended by 100 x 20 mm guns is defended by "light" flak while a target defended by a single 88mm gun is defended by "heavy" flak.
There is also a scene where the two heroes are pursued by a Hetzer tank destroyer,a vehicle whose only role is the destruction of enemy armour and would be singularly unsuited to the task of pursuing enemy agents.
On the credit side John Barry delivers his usual excellent score.
