Plenty of films go into Venice, Telluride, and Toronto with North American distribution already in place, particularly when you have the backing of a distributor like Netflix (which had four world premieres this fall) or Focus Features (which brought the house down with the likes of " Hamnet" and " Bugonia "). But with more than 300 features premiering at this year's Toronto International Film Festival, and a swath at Venice, Telluride, and now headed for New York, many venture in without distribution support.
