For background let me explain two shows: one that was made, and one that was not. The first show is Game of Thrones, which is currently HBO's most epic project and one its most popular shows. The basic premise is an adaptation of George R.R. Martin's fantasy series called A Song of Ice and Fire. Each season adapts one of the books from the series, which are generally in the ballpark of 1000 pages. So far both seasons have been 10 episodes.
This second show never got beyond the brainstorm process, so it doesn't have an actual name. It was a TV series to be based on the bestseller The Da Vinci Code made by the guys that brought you 24. The idea was rejected by Dan Brown, so nothing came of it. The book was later adapted into a largely forgettable--and thus forgotten--movie.
Now, let's enter a hypothetical universe, which is exactly like ours up to the year 1999. Let's say that other than what I change in this essay everything else happens exactly the way it happened then.
So, the year is 1999. Harry Potter is becoming an international phenomenon. Libraries and bookstores can't keep enough copies in stock. Warner Brothers approaches J.K. Rowling with a big wad of cash and asks to buy the rights to make the series into movies. Up to this point, things are exactly how they happened in real life; with the caveat that I don't know if Warner Brothers literally had a wad of cash with them when they acquired the movie rights.
But let's throw a wrench into things. Let's say J.K. Rowling says no. Maybe she realizes that the books are too long and complex to become a really compelling film. Maybe she wants to finish the whole series before she even thinks about optioning the rights. Maybe she's just content sitting on her millions until the right deal comes along.
So the years pass. Harry Potter stays a purely literary phenomenon. In 2008 J.K. Rowling finishes the final book, and decides that now is the right time to start adapting the books into another form. She has two bidders for the rights. They come to her living room each with a presentation for their plan for the adaptation. Group number 1 is Warner Brothers. They propose exactly the same movies that were made (with the exception that Daniel Radcliffe and the other child actors would not be in it, because they are now too old). They promise huge grosses. Billions of dollars in revenue.
Then in walks Disney. They explain they have a different plan. They remind Rowling that her books are very non-conducive to film because they are supposed to depict a whole school year, with individual happenings and adventures popping up every so often before a big, overwhelming climax. They point out that there are at least 50 characters in each book, and in a film you would have to cut down basically every character that isn't Harry, Ron, or Hermione. And they warn that character development will be non existent in Warner Brothers plan. And then they make their proposal.
Disney will use ABC to make Harry Potter into the biggest TV series of all time. They will buck the American trend of 24 episode seasons, and instead make every film as essentially a mini-series in 1 hour segments. They will put the Disney money behind it, so it will look as credible as an actual film. They'll make it back up in merchandise and in Super-Bowl like ratings. Not one aspect of the novels has to be cut out. They can spend extra time developing the relationships between all the characters (with Rowling's input, of course). They'll get Michael Caine for Dumbledore, and Matthew MacFadyen as Snape (given the fact that the actors who played those roles in our universe are getting on in years, and this is a 7 year commitment). They give her 100% veto power in all creative and casting decisions. For Disney, this creates something that can be a cultural event on Network Television, and keep its dominance over cable channels for the time being.
Let's say Disney can make this happen.
Which is the better plan?
