The sequel is not happening at least not on the big screen but there is a chance the tv series could still happen and get to watch parts 2, 3 and 4 that way!
They still have a lot of work ahead of them before the tv series becomes a reality and if it does get off the ground I hope Netflix takes it.
They would be perfect to show the tv series on there, we will see how far they come between now and the end of September in 2018.
I hope they will have it ready by then but something tells me it will end up being quite a few years before we see it if at all?

2016 was the first rumor and it's almost 2017. The sequel has been in development hell for years now. Though having said that, I hope one does get made. Though I'm not expecting anything at this point.

Looks like you might get your wish. There's a "Return of the Killer Clowns from Outer Space in 3-D" set to open in 2018!
I'll believe it when I see it.
That sequel has been rumoured for years.

I'm surprised Netflix hasn't done an original series yet.
