Check out the trailer to this little film Altitude. It takes the gremlin on the plane story to a whole new level. A "giant flying gape-mouthed octopus that lives in the sky" level. Take that, Cloverfield.
The film features a few TV stars, but is basically made up of unknowns, which we're always happy tp see. The basic premise is a group of teens board a private plane, and end up face to face with a giant sky beast. The end. It looks engagingly trippy — especially in the two stills we grabbed.
