The 8 Harry Potter movies were released in a span of 11 years...is this the most successful movie-making accomplishment of all time?

The first 3 HP movies were released within a 4 year period.The final 3 HP were released within a 3 year period.These movies were huge, blockbuster productions yet they were able to produce, write, film, edit, score, and release them within such a short period of time...all while maintaining the same quality of grandiosity, storytelling, and magic.A single movie nowadays often takes years from start to finish. Many movies are in production forever. Many blockbusters start their marketing a year (or sometimes more) in advance. Filming and release dates get delayed constantly.What the Harry Potter movie series has done will likely never happen again. via /r/movies https://ift.tt/2FGlQXs
