While most of the nation looks at crisp air and colored leaves as signs of the coming autumn, we look for red carpet.  The San Diego Film Festival is back and tonight the film Like Dandelion Dust will play at Gaslamp Theater to kick off four days of parties, schmoozing, special events and, of course,  films from all over the world in all sorts of genres.  Since September for us means extra-hot weather, check out the lineup to find a film or two to catch in the Gaslamp's finely air-conditioned theaters (and if you didn't get a chance last year to see Short Term 12 before it went to win Sundance, you can see it Thursday at 6 PM in the SDSU showcase).  Schedule, ticket information, and more at sdff.org.
