May I suggest you give Saxon Microlights a look?
www.saxonmicro.co.uk
Lessons available at North Weald in a Thruster T600N (a nose wheel version of the fixed wing aircraft in the film) .
You could also go and have a look at Rayne airfield just outside Braintree (if you haven't already). No training there unfortunately, but Saxon use it for cross countries and land aways.
PM me your details if you want a chat about organising a visit and to find out a bit more.
