"We haven't put on a night like this for a while so we want to show everyone that we're still fun, we still do fun and exciting things."
Mr Gordon encouraged people interested in buying tickets to buy them early as they were selling fast.
Every ticket sold will come with a goody bag, which will give cinemagoers free entry into the Lava Bar afterparty and the chance to win a prize pack, he said.
The movie is a follow-up to the 2007 film, taking place before, during, and after the events of 300. The cast will include such names as Sullivan Stapleton, Eva Green, Callan Mulvey, Hans Matheson and Jack O'Connell.
Mr Gordan, a self-confessed 300 fanatic, expected the movie to be action-packed and thrilling.
"It's going to be full of action, with all the blood and gore that made the first one so good."
Cinema worker Karim Nepia said he was excited to step into his Spartan sandals for the event. "We've all got our costumes sorted. The women's costumes are cool. But ours, they're more like dresses, but it'll still be fun." He said many staff members were fans.
