Hello,
We are a Film Location House and we provide Fixing Services in Greece.

Regarding VISA if a US were to come to Greece for filming our company should send a letter of invitation to the Greek Embassy in the city you are based (say LA) with the names, passport no, speciality (eg Producer) stating the purpose of your project and the timeframe of stay in Greece.
Regarding permits for filming in public places within the boundaries of Athens Municipality there is a fixed price for every filming spot of shooting and it amounts to 1335,29 Euros per spot per day. Of course there is always room for negotiation since someone has a workflow kind of relationship with the Athens film office and since there is a volume of locations with permit need. This could even shrink the cost up to 1/3 of the total price sometimes.
For Ancient / Classical / Protected etc monuments the shooting cost can be lower but there is a license cost added ranging on the use of the final product (eg theater release, internet, publishing on catalog, broadcast or else…) and it can take up to a month of process and approval of content from the Archaeological council to decide and confirm.
There can be a big variety of public places with low or no cost permits at the suburbs of Athens or in some islands like Mikonos, Corfu etc)
It is always essential and advised for a better quality, easier and faster access, deal potential and local knowledge issues to have a local Fixer / Company to handle all practical issues for a foreign production visiting as long as there is mutual flexibility chemistry and trust.
Hope this information helps.
Best Regards,
Kostas Tagalakis
