However, Economic Development president Peter Ferbrache said that the important thing is that the film gets made.
'In an ideal world of course I want them to film some here,' he said.
'If not, then so be it – it's not a bad second-best because it's still going to publicise the island.'
A spokesman for the production company said that they were sad not be able to film here: 'We could not logistically make it work,' he said.
Producer Paula Manzur had visited and been in close contact with States departments over the years and 'absolutely fell in love' with the island, so was disappointed that shooting could not take place locally.
But while exteriors are due to be filmed in Devon, he said the film would nonetheless promote Guernsey: 'This is an international movie which will very much be an ode – a love letter – to the island itself.'
