Tremors 8

 Another movie that would never get made I have a sequel idea for. 

And I would call it: Tremors 8 Everyone

Pun intended. 

Michael Gross would be reduced to cameos through recorded messages he left for everyone but in Perfection after his death in 7. (SPOILERS) 

It would bring back almost every side characters from the previous movies minus the brothers Kevin Bacon and (RIP) Fred Ward. 

The worms have returned to perfection and are devouring them all. Without Burt to hunt the worms Jamie Kennedy is the town's only hope but even he isn't good enough. So you bring back Reba Mcintire (by backing up that money truck to her front door in an attempt to get her to do it) Who saves the day (again after several sequel and TV characters are killed off) to save and settle back into Perfection, where she lays Burt's old guns to rest. 

The stinger after the credits would be Burt doing one last video proclaiming love for his ex-wife....and then providing the coordinates to his whereabouts on Shrieker Island. 

BOOM!
