A worth-sharing chart (below) created by USA Today, which doesn't necessarily tells us anything we don't already know (that sequels, prequels, spin-offs, reboots, remakes, etc dominate Hollywood studio filmmaking today - specifically, the summer blockbuster movie season). But it's always nice to see the raw data charted.
You can see just how much the *original* screenplay has gradually been supplanted by retreads over the years. In 1993, as you can see, only 3 movies (out of 20, or 15%) released that summer were make-overs of some kind. 20 years later, in 2013, eleven out of 20 summer movies (or 55%) are retreads.
In 2007, a whopping seventy percent were redos - the highest in recent years.
I imagine, if a similar chart is created in another 5 years, that percentage will be even higher. Next summer (2014) is already shaping up to be another season dominated by sequels, prequels, spin-offs, reboots, remakes, etc.
To wit: X-Men: Days of Future Past, How to Train Your Dragon 2, The Amazing Spider-Man 2, Dawn of the Planet of the Apes, Godzilla, Fast & Furious 7, Sin City: A Dame to Kill For, Teenage Mutant Ninja Turtles, Untitled Transformers Sequel, 22 Jump Street, Maleficent, and Hercules... to start.
That's already 12 right there.
Also, the last time a movie that wasn't a make-over topped summer box office was in 2003.
Check out the full chart below. Although I recommend the chart that's on USA Today's website, since it's interactive - as in, putting your mouse over each colored block will open up a pop-up window with film titles and domestic box office information.
