Virtual filmaking is a concept that's not new to those folks involved in machinima, a hobby of using character models, sets, environment and engines in video games to create short films and comedy. However, one aspiring filmaker has gone and made a serious nearly 2 hour film entirely in the engine of Grand Theft Auto IV. While the dialogue and voice acting are pretty amateur, the direction, camera work, music and overall story are quite outstanding! You can see the entire film for yourself in the video embedded below. A fair warning though, the movie is meant for mature audiences as it deals with violence and nudity and locales that those who're familiar with the GTAIV game know quite well. The fact that the movie came out as well as it did is a testament to the great work and detail put into the world of Liberty City by Rockstar Games.
