Someone on Facebook told me about a trailer for a documentary called "Breathe" about a free diver trying to hold his breath and go deeper and deeper under water.
Check out the trailer

Not only is it shot well but the trailer is great because it reveals bits of information that when weaved together (with nice editing, shooting, etc) the 2:40 trailer makes you want to know more and you want to see it to know the finish and more, that's what I took out of it.
