The moon over the Pole will be above the horizon for 2 weeks and then 2 weeks below. Around midwinter, when the sun is the lowest the moon will be fullest when it reaches the maximum elevation which can range from 23.5° ± 5°. 2015 the moon won't get much higher than 18°.
For the movie the biggest challenge is like always the cold, even operating the camera in a heated box, this time also adjusting the exposures for different phases of the moon and different elevations.
Also the weather is a big part, we were lucky to nearly get 2 weeks of good weather in one piece, which is very rare here.
