Who would be the audience for your media product?

As our genre is western i decided/knew from the start that the audience for my media would be a niche audience. This is because westerns are seen to be quite an old style of film meaning that the niche market would be from the older generation. But recently a new film has came out called "True Grit" which has been realesed as a certificate 15. Also True Grit is recieving alot of good press and i think the audience for this particular western will be alot larger than what i would see an old western such as "Monte Walsh" which audience has shrunk due to it being 'unpopular'. So it is quite possible that the audience for my film could of grown during the period of time from the storyboarding to the finsih product due to this new western film.
