This camera (or one like it) can shoot 240 frames per second.  If you multiply 90 minutes times 60 seconds times 30 fps you get 162,000 frames to make a feature length film.  Take that number and divide it by 240 and again by 60 seconds and you see that you could record a 90 minute movie in 11 minutes and 15 seconds.  Shoot fast, play it back slow.


That is some simple math, but what would the story be?  


You couldn't record sound, so any monologue/dialogue would have to be recorded and dubbed in later... and you couldn't lip sync at that speed, so I would focus on telepathy or only internal thoughts. Something like... people's thoughts in the last moments before a disaster strikes.  With green screen, you could add a main character in later who moves in real time. A scifi premise where the main character is out if sync.

You are a lone researcher on an outpost planet. You are contacted by mission control to tell you that a rogue planet has entered your solar system and will collide with your planet. That’s the bad news, the worse news is that they can’t get a rescue ship to you in time.  Oh and it is going to continue to take out the moon orbiting the planet and several other planets in the system.

Your only hope of survival is to find a way of hopping from one celestial body to another staying one step ahead of Planet X.

Inspired by a short story by Italo Calvino, “The Distance of the Moon”  http://www.aleastory.co.uk/The-Distance-of-the-Moon.pdf

“This is how we did the job: in the boat we had a ladder: one of us held it, another climbed to the top, and a third, at the oars, rowed until we were right under the Moon; that’s why there had to be so many of us… from the top of the ladder, standing erect on the last rung, you could just touch the Moon if you held your arms up…. I would cling first with one hand, then with both, and immediately I would feel ladder and boat drifting away from below me, and the motion of the Moon would tear me from the Earth’s attraction. Yes, the Moon was so strong that she pulled you up; you realized this the moment you passed from one to the other: you had to swing up abruptly, with a kind of somersault, grabbing the scales, throwing your legs over your head, until your feet were on the Moon’s surface.”

The solar system that you are in is very compressed and and each planet has multiple moons with wildly elliptical orbits, which at times take them so close to their planets and each other that they are almost touching.  

So the game play is to build structures to be able to transfer from one body to another when they cross each other’s path.  Each Planet/Moon being a level with it own unique problems (i.e. different gravity, raw materials, distances to transverse, lack of oxygen, etc.)

Fighting game where all contestants have a wolverine-like ability to heal. You would have to create a fighting system where the player models could be cut(deformed) and sliced(cut in pieces).  If a player's arm or leg is sliced or blown off, it starts growing back. You would need a system that adjusts the fighting moves dynamically based on the body condition, and a system to manage the body model. 

You could probably build the body in segments and create versions of each segment that animate the segment's growth.  The body would use a dynamic IK system to string together the pieces to form the whole.

You have to take the head to win, the theory being that if you sever the connection between the head and the heart, you break the ability to regenerate... that is why severed limbs don't grow into a copy of the original.
