Ok very vague description here, it’s gotta be a horror movie from the mid to late 80’s, but all’s I remember is a scene where monsters with large mouths picking people up and stuffing them in their mouths. Thinking back they were obviously people in costumes with mouths large enough to stuff people in. Probably silly now but as a 7 or 8 year old it freaked me out!
I was thinking along the lines of the Gate but that’s not it. Ring any bells?
