How meteorologists recreated weather that helped decide second world war

Experts helped guide weather scenes in Pressure - a film depicting dramatic buildup to 1944's D-day landings

Dressed in a Royal Air Force uniform and sporting a trim moustache, Andrew Scott looks slightly queasy - as well he might. Behind him is a huge map of the Channel, and in front of him is Brendan Fraser, looming with a request: I need a forecast," he says.

Starring in the film Pressure, based on a true story, Scott plays the meteorologist Gp Capt James Stagg - the man who must tell Gen Eisenhower - played by Fraser - whether conditions will be suitable for the D-day landings scheduled to take place on 5 June 1944. But a large storm is approaching the Normandy coast.
