Swarm was directed by Tom Harper, of Misfits, The Scouting Book for Boys and This is England, and written by Geoff Busetil, of Skins, and Daniel Kaluuya, probably best recognised as an actor from The Fades and Black Mirror.

What a relief. That could so easily have been clogged with product placement.
