Has anyone seen Mad Max 4?

I mean: has anyone actually seen Mad Max 4, not just like posters and ads on rare occasions but like the actual film?
I seriously doubt that it even exists. I saw an ad for it and a trailer a while back but I cannot find anyone who owns a copy or that has even seen the film. I don't think it even exists.
