"The Swarm" is a short sci-fi film directed by Tom Harper of "Misfits" and written by Geoff Busetil of "Skins." And it was shot entirely on a mobile phone.
Enter The Freeman, a decidedly incredible short that was "shot by fans over two nights in a cottage in the middle of Hollywood for about $3000."
Everything is top notch, especially the live-action Gordon Freeman. Nailed it.
