Because sci-fi movies usually rely so heavily on a compelling core concept or hook - time travel, a dystopian future, apes on horseback, you know, your typical fare - it's easy to understand why they're so often subject to remakes.
A fantastic concept is a fantastic concept, whether its made in the '40s in black and white or in the modern day with an IMAX camera, making sci-fi an incredibly endurable genre, a trait that lends itself well to frequent reimaginings.
And while remakes and reboots are commonly viewed as quick, lazy cash-grabs (and in some cases, they are) they're never a bad idea. If an older film has a great idea it didn't fully explore - like 1990's Flatliners, which will receive a remake later this year - what's wrong with a new team taking that idea and fleshing it out, expanding upon it and refining it?
There are a bunch of sci-fi remakes in various stages of production, whether stuck in development hell or quickly moving along, so let's take a look at a few you may not know are slated to hit the big-screen soon...
8. The Blob
This next remake of The Blob will be a remake of a remake, following the first remake - in 1988 - of the original 1958 movie.
Confused? The remake we're discussing here will be the third iteration of this story, after the 1958 and 1988 versions. Just to clarify.
Both existing versions of the Blob depict the struggles of a small community against a giant amoeba-like organism that dissolves and devours anyone unfortunate enough to be caught in its path.
Remember those small tubs of putty you used to play with as a kid? It's essentially that, but huge, sentient and deadly.
The upcoming remake will star Samuel L. Jackson (he's had it with this motherf*cking Blob), and, according to some recent rumours, Halle Berry.
Simon West (Con Air) is set to direct the film, and according to him, this version of The Blob will be on a much bigger scale than the previous ones (both took place in a small American town), and the creature itself will be smarter and more sophisticated, along the lines of a Xenomorph or Predator.
If that sounds weird, don't worry! The Blob will still be The Blob. The 1958 and 1988 versions were quite cheesy and very much of their time, so all this version will do is bring the monster up to date for modern audiences.
