A fully digital 90 minute movie named Hell Grind was shown at Cannes. It took 14 days to generate at a cost of 500k and it's fully digital. From the trailer the movie itself looks terrible, but as a tech demo and proof of concept pretty impressive. The AI characters definitely get into the uncanny valley at times but at other times you could sell me that they are real flesh and blood actors. Pretty crazy what they are going to be able to do with this in a couple of years.
