While once upon a time TV was cinema's poor younger sibling, the same can't be said today: TV shows now offer an incredible breadth of storytelling that can at times surpass what's offered on the big screen, and some shows can bring the cinematic spectacle to match.
In that case, it's maybe no surprise that more and more movies seem to be getting the TV treatment. Hollywood isn't exactly known for its originality, so if it can take a pre-existing movie, and extend that out into a multi-episode season, then that's what they're going to do.
It's nothing new, of course, and there's a long, mixed history of stories making the transition from the big screen to the small one. M*A*S*H was an early success story back in the 1970s, and since then we've had the great (Fargo), the terrible (Uncle Buck - both versions), and the WTF (Ferris Bueller).
TV can ruin a beloved film, or take a film no one liked and cared about and turn it into something truly special (hello, Buffy The Vampire Slayer). It's a risk, but one network execs keep on taking. Although a number of planned TV shows based on movies have seemingly disappeared from existence, like Shutter Island and Big, there's still a lot to look forward to, or, in the case of these 9, not.
