Since the festival is only for one day..and they plan on having a big panel discussion and the like...I personally thought that they were pushing it to squeeze in two films.
It would be great if they had more, but I don't know that time would warrant it.
Most of the directors and actresses---that are still living---are based in Europe. As this is the first shot at a Festival...I doubt the funds are there to allow them to bring in many, if any, folks from overseas. I know they have invited several though.
And don't forget....there will be many more celebrity guests to come (they say). So, what they show on their website isn't the definitive list.
For example, I know that John Saxon is going to be there; but, they don't have him listed, yet.
I would imagine that budgetary concerns are an issue with the number of films that are being show, as well.
I am just glad to see that someone is trying to hold a Spaghetti Western related event here in the USA!
