Fans have taken it onto themselves to make movies in their favourite universes before but this a whole new level!
In June last year a rather unusual Kickstrter appeared, aiming to fund a short about returning crusaders fighting the greatest killing machine in the fictional universe! Helmed by accomplished director James Bushe, who also co-wrote the project and featuring actors such as Adrian Bouchet (Alien vs Predator) and Jon Campling (Harry Potter and the Deathly Hallows: Part 2, Sleeping Dogs).
With the help of just 159 people they funded this masterpiece, which they have now delivered to the world via youtube.
The only reason I can see to refer to this as a fan film is licensing
