There are dozens of original series era fan films. Take a peek: http://startrekreviewed.blogspot.com/2009/06/2.html
Blogs 20 through 55 all have fan film producers who have produced Fan Trek set at the time of the original series or the original series' movies. That doesn't include short films, or very old films, e.g. http://startrekreviewed.blogspot.com/2009/06/204.html
(See also other lists in Blogs 205-208), and many more are in the works. The fight about this is dumb. The TOS sets in upstate New York could probably be used to produce more than a dozen films a year, and there are sets in Georgia and Oklahoma which are also very good, there is a lower quality set on Long Island and a movie era set, in Albany, Ga. Then there are green screen productions. Geez Louise, one person playing Kirk at this point no more means another won't than one person playing Hamlet means another won't.
