I remember this scene from a movie I don’t remember. It had people with guns getting into this living room with a little boy, and then I think minutes later some guy gets attacked by some snake creature that had four fangs (It didn’t look a lot like a snake from what I remember) and it cuts to a scene of the little boy with cracks on his face? And the snake thing is seen crunching on something and a little bit of dust? Falls from its mouth.
I was little when I saw this scene, I’m pretty sure it was late 90’s or early 2000’s.
