I love these mashups of repurposing movie clips as trailers that make the movie look like it’s a completely different genre.
Case in point, this trailer for When Harry Met Sally that makes it seem like a horror movie. It also shows the power of music to set a mood.
Of course, it also works in the opposite direction as well. Such as this Quicktime movie that makes The Shining look like a romantic dramedy.
