There is an interesting new festival with few guidelines looking for content, mostly shorts but perhaps longer. I would throw some less-seen shorts of mine there but they have to be premieres. It would still get more eyes on a short than your own personal platform of channel. I am considering making something new.
It is run by Robert Meyer Burnett who directed a movie called Free Enterprise that featured William Shatner and has this great Shakespeare rap set piece, which is a great example of a concept floated in a movie as “crazy” that turns out to be very entertaining as executed.
