After writing and directing one of the worst movies ever committed to film with 2007's Aliens vs Predator: Requiem, Colin and Greg Strause, AKA the Brothers Strause returned to direct and produce 2010's critically panned Skyline, considered by many as the poor man's Battle: Los Angeles. Few would have believed then that after seven years of absence after having made two critically panned movies in a row that the Brothers and their visual effects company Hydraulx had even survived, never mind was still in business in Hollywood. Yet the Brothers Strause (and their company Hydraulx) do indeed return, though thankfully only in the role of producers for a follow-up to Skyline.
The events depicted in Beyond Skyline, Starring Captain America: Winter Soldier's Frank Grillo, run parallel to those depicted in its predecessor.
