Where can I find movies blurbs (short movie tag lines in one or two sentences)?

Question

E.g. : Alien : In space, no one can hear you.
Superman : You'll believe a man can fly.
The Core : The only way out is in.

Answer 1

If you go to the site below, and put the movie title in the search box (upper left of page), a page comes up that tells about that movie, the actors, etc. From there, scroll down to "Quotes" and you'll see the blurbs you're looking for...they show a couple, and you can click on "more" and there should be an entire page!

Answer 2

IMDb.com has this information in the listings for most major films, but you'ld have to search by title
