Filmmaking / Directing : First feature film with international cast, crew & locations -pros and cons- by Daniel Latteo

Hi there. My name is Daniel and I'm a Filmmaker from Italy. I'm writing a script for a very dark and quite original Horror/Witchcraft feature. By the way it's coming out I can envision half of the cast, and consequently half of the crew to be International. It will also I think, from a creative point of view that is, help the project to be more effective and break the boundaries of countries, cultures and races. To make it clearer to you so you might want to give opinions and/or advice about it, I'm thinking of developing this project very similarly to the way Italian film director Dario Argento developed his Suspiria back in 1978, where he had half of his cast all International; Joan Bennett and Jessica Harper (Usa); Udo Kier (Switzerland); Rudolph Schundler (Germany) Alida Valli, Stefania Casini and Flavio Bucci (Italy) Miguel Bose' (Spain). He also had a few key crew members that were from abroad and of course the films was shot in various European locations, prominent of which were Germany and Italy. In analyzing the plan for my film I see a lot of similarities between that development and the one that I will have to go through, especially on the logistics of it, the creative approach and the aesthetic flavour. What about it now? Do you think it is too ambitious to aspire at something like this? Do you think it is a possible plan for a first timer? Has anyone among you already done something like this? If yes can you tell me what logistical, technical and production problems you had to overcome? Any help is greatly appreciated. Thank you all. Daniel
