I've been going to Park City for a long time. In fact my first year was 1991 with How to Kiss and that was the famous Sex, Lies and Videotape year that put Sundance on the map. The next year I premiered my first feature The Tune there and got to meet and hang out with Quentin Tarantino. He knew more about my animation than I did!
Recently I was invited to show my short film "Santa, The Fascist Years" at the wonderful alternation film fest Slamdance.
I was the short before the feature Down Terrace by Ben Wheatly. This film had been picked up by Magnolia and it is one of the strangest darkest funniest film I've seen in a long time - a sort of sick Sopranos in England. Another excellent film is called And everything is going fine it's a documentary about Spalding Grey and his life leading up to his suicide using only footages of his taped shows. It was created by his friend Steven Soderberg who couldn't be there but made an appearance via skype.
I highly recommend Slamdance, send your films (shorts or features) to this wonderful festival. They really keep the indie spirit alive, and it's a great experience.
