I just sent a copy of my film "Calls of the Wild" to the NW Animation Festival in Portland, OR.
This seems to be one of the few festivals that has no restrictions on the films that are submitted (any length, completed any year, online availability, etc.) It feels like a pure film festival, one unconcerned with premiering and being "the first." Hopefully, their only interest is to shown great animation.
Here's hoping I get selected!
