In case you weren't already aware, the PC version of Grand Theft Auto V comes with some very impressive tools for people to 'exercise their creative muscles'.
Around one hour after the games release, someone had already made a spectacular film using only the editing tools provided within the PC version of the game. The Video is called "Running, Man" and it is directed by 8-bit Bastard.
He was actually given early access to the editor by Rockstar themselves, but I am not certain how long he has had access for. Judging by the quality of the finished film, I would say a week at least.
I'm very impressed by the quality of the film and it highlights a lot of great features within the editor!
