This is a neat video. The whole idea of it was that they had up to 1500 people develop a small 15 minute or less segment of The Empire Strikes Back. However, the focus was not on live action alone, people were allowed to use any type of animation or video content in any way they wished, they could use puppets, 2D/3D animation, whatever it took to finish their segments.

I'm not sure how the collaboration was developed  during the collaboration, but apparently up to 480 segments were to be combined to develop a full movie version of the submissions. It's The Empire Strikes Back movie with a twist. Sort of an experimental film.

It's cool seeing all the different ways the contributors used to achieve their goal, along with the different ways they attempted to develop the digital effects and otherwise. Some would do their best to completely mimic the segment shot by shot, others decided to go with their own ideas..... Some used puppets, others animated, and more...

Plus its not a full imitation, some segments throw in gags or jokes, or a funny twist on the scene.
For example, in the asteroid scene someone made it seem like a game of asteroids.
I could name more stuff than that because the astroid gag itself is not that original but I do not wish to spoil the video.

Apparently it is even approved by Star Wars itself, because it is on the Star Wars channel.
I'm not sure if they were the ones who started it or not....
I would love it if there were more collaborations like this for other movies...
Hell, I hope they do Episode Six as well.

Whether you’re a Star Wars fan or not, it's pretty neat to check out.
Give it a watch if you have some spare time.
Perhaps they will have another contest you can contribute in.
