We just completed a film shoot in Europe, Costa Rica and the US last Nov and Dec. 05. After discussions with Kodak reps in the US and UK, we were given, the following suggestions: In Europe, the scanners for hand-carried film are not a problem, but checking film as checked baggage is not recommended, especially in and out of Heathrow. The Kodak tech rep in London assured us that many productions were hand carrying film on a daily basis all over Europe, so we took his word for it and safely carried rawstock and exposed footage with us (when we had to) as carry on while we were working in Europe.
In the US, Kodak's advice was "don't handcarry or check anything on a commercial flight, send it Fedex". So we did just that. Our exposed film (ASA's 100 & 200) was indeed sent via Fedex from Europe, New York and Costa Rica back to our lab in Burbank without any problems.
If it's any consolation, it's been our experience that most emulsions of Kodak film are available worldwide at roughly the same price as in the states. Even in Costa Rica we were able to buy it from a local reseller.
Where you pay more is in countries with high VAT's, and can discuss this with the local Kodak rep on reclaiming that when you leave the particular country. Hope that helps... John Fante
