Although an iconic character like Green Lantern might be an exception, I don’t know who would put up the money for a project that would both need a big budget and had failed previously.
To get back to Adam Savage’s point, there are plenty of movies out there with interesting premises that could be rebooted and made better.
Still, if money were no object, those would be the movies that could really have new life breathed into them.
He named a Molly Ringwald film as an example, but what if something like Waterworld or Green Lantern could be remade to be less of a disaster?
