Why don't you try to get your film in a smaller or even local festival and then have that as 'rank' for when submitting it to a larger festival like Canne? I know a few people who have done this and their films have gotten bigger for each festival....and this is coming from the Caribbean.
You think inde america has it bad....you can't expect to imagine how a region not known for filmmaking has it.
small steps by friend. Complete the obstacles you can. It works.
Good advice. Really study the festival you are submitting to and make sure they cater to the genre, style, budget, etc that best matches yours. Your chances will improve and the attendees, reviewers, etc . know what to expect.
As far as being from a region not known for having a filmmaking community - turn it to your advantage marketing wise. Remember the Jamaican Bobsled team.
