Others expected at tonight's premiere include Temuera Morrison, Keisha Castle-Hughes, director Andrew Adamson, Karl Urban, and cast members from Shortland Street and Crouching Tiger Hidden Dragon 2, a Hollywood sequel shooting in New Zealand.
Produced by Tom Hern, The Dark Horse will screen just once at the Auckland festival before launching the Wellington festival next Wednesday. It opens in cinemas at the end of the month.
It's based on late Gisborne speed chess champion and bipolar sufferer Genesis Potini, played by Curtis, who starts teaching chess to his nephew Mana, played by Rolleston, and an unruly bunch of Gisborne kids to keep them out of trouble.
Robertson said he had been privileged to meet and play chess with Potini and had worked closely with his wife Nat and son Nopera on the film, who along with Shane Fitzgerald and Noble Keelan, who had inspired the characters Jedi and Noble, were being flown from Gisborne to Auckland for the premiere.
Festival director Bill Gosden said although there had not been a public viewing of the film, industry feedback had been glowing. "I think the word is out that it's a great film. Not many people have seen it, but I haven't met anybody among those industry people that have seen it and hasn't been persuaded that it is going to really hit a nerve in New Zealand."
The only other film which he could recall being such a sell-out was when Love Story directed by Kiwi Florian Habicht launched the 2011 festival.
Another New Zealand film, Gerard Johnstone's Housebound, will premiere during the second week of the festival and Mr Gosden expected the horror-comedy would be popular.
The two children's films, Toons for Tots and Animation for Kids, showing at The Civic were also proving hits.
The festival runs in Auckland from July 17 to August 5.
