After browsing Google for "short action movies", I came across this short film. I was a bit surprised since I'd heard of the feature length version a few months ago. Then I found out the original (this one) is the original film and it's available on YouTube. I gave it a watch, and was highly impressed by the special effects, action and tension delivered in 10 minutes. Some fine performances are also what this film can boast. It's something you can go back to again and again, given how crisp, well made and immersive it is as any feature length blockbuster.
