...the opening scene shows an people entering an airplane which flies into the air...then all of a sudden it enters into space or something....and earth is completely empty where these big "mouth" monsters ate up everything on earth, even the land itself. Yeah I know, it was a film that freaked me out.

Do any of you guys know this movie? I'm dying to know.

P.S. I think it might be a film based on a Stephen King novel (horror)
Thanks guys
