The makers of the latest X-Men movie, which is being filmed in Queenstown, need more time to shoot the project.

The company making the $100 million blockbuster, Woz Productions, has applied to vary their resource consent. It wants to extend their filming period from March to April, as well as double their helicopter movements from 10 to 40 each day.

The production has already caused controversy in the resort town, after the filmmakers were told to remove explosives from the Queenstown Fun Centre.
