The teaser trailer may be just that

I would just love for the Blue Guy to be a Red Herring. Riddick does not belong in this film. Also for the next trailer, I would just love for a voiceover by none other than John Hurt himself. That would be a nod to all the fans that yes this is Alien - no Ripley, no Starbeast but it still is Alien you're looking at. "They went looking... For our beginning.... What they found... Could be our end..." in the husky, raspy throaty, voice of John Hurt. Would be cool.

Listen right... Right, you guys on here are big fans, right... Like really big fans of Alien and Prometheus, right... Right, well the thing is, you see, right... I am Ridley Scott, right...
