The video below is his most recent piece of work (entitled "Break 3"), that takes advantage of the Halo 3 Microsoft Engine to tell the silent story of a prisoner breaking out of jail (but there's a long way between getting out and being free!). It is a simple, fast-paced chase movie that impressively makes use the Halo 3 engine to recreate the sort of camera shots that you would expect with major movies.
Nicholas Werner is a Stanford graduate that has made several movies based on computer game engines for Machinima, many of which to great acclaim. I shall endeavour to include some more of his superb work in the near future (including the EPIC "Deserter" and the very impressive "Potentior", a movie that traces the events of the final major battle in the Gallic Wars, the epic struggle between Julius Caesar and Vercingetorix focused on the siege of the fortified town of Alesia - all using the "Rome: Total War" game engine!).
I look forward to more of his work.
