Here on Trulia (a Real Estate Web site) Realtors in San Antonio may be much less aware.
But I personally know this is getting to be a bigger event each and every year. Not only is it a film festival, but a music festival as well where many musical artists are show cased during the events and quite a few of those bands have performances here as well in the Alamo City.
It is a great event where so many talented people gather. You may think most stars live out in Hollywood, but we Texans have Sandra Bullock in Austin and Tommy Lee Jones here in San Antonio, just to drop a few names.
So 'my' answer to your question would be a big "YES" ! ! !

There may be some spill over to San Antonio, but if there is, it is really not hitting the masses. Its clearly a lack of good marketing on their part.
Sad thing is... if they promoted it better, it would be a big hit!
I've lived in other areas that had these festivals and if you asked locals who lived within a one hour drive, they wouldn't even know there was a festival. One time I had a full set of passes for a 4 day event and I had trouble finding someone who was interested in going.
