After Nelson Carvajal made his Boyhood and Planet of the Apes mashup trailer Apehood, film writer David Ehrlich tweeted that the idea "would have been much more effective with Harry Potter." Well the folks at Slate took the idea and cut together this Potterhood trailer. Although if Potterhood were an actual film, it would be about 19.5 hours long and still probably manage to hold my attention longer than Boyhood. Get it? Because Boyhood was boring. The movie spanned twelve years but you felt like you were watching it for thirteen.
