Swords, armour and bronzed biceps will be on show at the upcoming opening of 300: Rise of an Empire.
Rotorua's Reading Cinemas will be celebrating the release of the fantasy action film, the sequel to the popular 300, on March 6.
Three hundred tickets will be available for the opening event, for which the cinemas will be decorated and staff decked out in Spartan costumes.
Cinema complex manager Ethan Gordon said the event was an exciting chance for Rotorua 300 fans to dress up like Spartans, have a good time and be in to win prizes.
"I think it's going to be a lot of fun," he said.
