Ridley Scott reveals the connection between his two sci-fi films.
Here's the English translation via AVP Galaxy:
"When the first Alien movie and Blade Runner were made, I thought that in the near future the world will be owned by large companies. This is why we have the Tyrell Corporation in Blade Runner, and Weyland-Yutani in Alien. They sent the Nostromo spaceship," said Scott.
"The Prometheus is owned by an entrepreneur called Peter Weyland, and is played by Guy Pearce. That's the connection between the two films, and nothing more. Prometheus is a new film, a new world, and is full of new ideas. And of course new monsters as well."
Pearce's role is said to be little more than a cameo, taking a mere minute or so of screen time.
