In the sci-fi thriller Skyline, strange lights descend on the city of Los Angeles, drawing people outside like moths to a flame where an extraterrestrial force threatens to swallow the entire human population off the face of the Earth.   Skyline is directed and produced by the brothers Strause (Alien vs. Predator: Requiem), whose company Hydraulx has provided visual effects for Avatar, Iron Man 2, The Curious Case of Benjamin Button and 300.
