Cat-alyst

Had watched this film when I was 6, and even if I have forgotten its title, I never forgot the horrifying and traumatizing memories it gave me, even to this day. Been blabbering about it with my relatives/friends or scouring the internet hoping to find it, but to no avail. 14 years later, I found it when searching for "movies with alien worms." Damn, why did I not think about that sooner? Definitely gonna watch it again!
