A sequel to Ridley Scott's wildly popular 'Alien', the James Cameron-directed sci-fi movie smashed records when it debuted in 1986, reported Digital Spy.
Sigourney Weaver, Michael Biehn, Paul Reiser, Jenette Goldstein, Bill Paxton, Lance Henriksen and Carrie Henn were all on hand to celebrate the film at a recent convention in Calgary.
The stars took to the stage at the Comic and Entertainment Expo, where they posed for pictures and discussed the legacy of the movie.
Biehn said, "You just kind of fall into the same personalities, the same friendships, the same thing we had 25 years ago.
Scott is currently working on a sequel to 'Prometheus', which is set in the same universe as the 'Alien' films.
