Batman vs Superman: Dawn of Justice recently debuted its final trailer, so while we might not get much more new footage before the film finally releases on March 25th, Youtube user M1llion has spliced together every trailer and TV spot into one compilation.
The better part is that M1llion put it into chronological order. I've seen a lot of spots and trailers for the film, but there was still some footage I had somehow missed along the way included here.
It should be noted that for the people who would say you could watch this instead of the entire movie and get the same effect, that really isn't the case. It is 9 minutes essentially out of a 2 and a 1/2 hour film, so there should be lots of great stuff still left to reveal.
