Just had it confirmed from the Festival committee:
Official premiere Sintel: Monday 27 september, 19:30h, in Rembrandt theatre, Utrecht, the Netherlands.
This screening is part of the normal festival, for which tickets have to be reserved or purchased via the theatre or via the festival itself.
Netherlands Film Festival website. (program will only be available sept 9)
The DVD production has also started (slowly!), we plan to have this ready for print at the festival. I’m uncertain if we can have the DVDs available then already though… we’ll do our best!
In order to prevent crappy bootlegs to be posted, we’ll release the film a few days after the premiere as well, with sufficient mirrors for everyone to enjoy with us this milestone in Blender history!
