Which is your favourite Alien movie?
All that talk about Prometheus having strands of DNA from the original Alien movie was a load of crap. Prometheus is chock full of Alien bits and pieces.
Have a think and choose wisely (I included Predator 2 as that has a glimpse of an Alien skull on the Predator spaceship).
If you are still thinking have a look at this remake of the Prometheus trailer made with paper.
