Films within games - also known as machinimas - are becoming increasingly popular on YouTube and with gamers.
In a nutshell and in the strictest sense of the word, it's using a videogame to create a cinematic production. Grand Theft Auto V, which is due to be debuted on PC, has taken machinimas to its heart and released the Rockstar Editor.
As this little trailer shows, you can create your own scenes, dialogue, music and anything else you want to make up your own scene.
Fancy recreating the opening scene in Heat? Or what about the moment in When Harry Met Sally when Billy Crystal tells Meg Ryan he loves her?
The possibilities are endless, folks. We're going to be recreating scenes from Fair City with this and casting Bella Doyle as Trevor Phillips.
It's gonna be incredible.
