I saw this a while ago and was thinking about it recently so I thought I'd share it again for anyone who hasn't been lucky enough to see it.
A YouTube user named JosephsBrett recut the trailer for the forever famous Ferris Bueller's Day Off by John Hughes and used Indie music and the result is something really amazing. Seeing it this way shows you that this film could easily have worked either way, all depending on the edit and change in music because it's surprisingly John Hughe's most visually impressive film. You don't think of it that way in the context of an 80's teen comedy, but watching it like this shows you how impressive it all really was. Kudos must go to JosephsBrett for doing such an amazing and time consuming job.
