-I recently watched Ridley Scott's fan-favorite classic Alien (1979) starring Sigourney Weaver and John Hurt. A link to the IMDb page can be found here: http://www.imdb.com/title/tt0078748/?ref_=nv_sr_2

-This movie revolutionized the horror and "A.I." genre in movies. Although I believe it was a little bit before its time, this movie was very entertaining. Had I watched this movie maybe 25 years ago, the horror aspect would have been more prominent. Today's movies are far scarier so therefore it was not as frightening as it would have been to someone in the 80s. A spaceship in deep space that is used for mining is under attack by an alien. Sigourney Weaver is a lone survivor, along with a cat, as she struggles to survive. The aliens evolve while on board. My favorite scene in this movie was when the alien popped out of John Hurts stomach. It was very gruesome and portrayed the nastiness of the alien. 8/10.

-This movie, although entertaining, does not have much scientific background. Alien movies are able to push the limits of normal thinking, because there is not definite evidence in order to study. This way, film makers have a bit of lee way when creating movies and don't have to follow scientific thinking as much as normal. However, there are still constraints to evolution that were ignored in this movie. The alien, which starts off as a small creature smaller than an average house cat manages to grow to larger than a human in a short span. There are many reasons why this is not possible, firstly with the physiological constraint. The amount of food that would have to be consumed is astronomical to have it grow that much that fast. Natural selection can be a fast moving process, but within one generation, this is not possible. Such a simple creature over the course of a few hours grows up to 10 times its size. It would be interesting if specimen were able to grow exponentially like this, but I'm afraid that the big screen stretches the truth at times.
