See entire movies for FREE!

I can see lots of movies for FREE and completely legally? How do I do it? (No this isn't copied out of spam.)

I simply watch the movie's trailer.

I have noticed an increasing trend to show the entire plotline of the movie in two minutes. To illustrate: The Italian Job trailer starts out with the heist, the back stabbing, through the revenge plot, through the execution of the job (the truck falling down into LA's subway tunnels, the car slicing up by the helicopter blades etc.) all the way to the very last scene in the movie of her punching the bad guy. Ugh. The entire frigging movie is there: no surprises, no scenes that we didn't see. Well, maybe one with machine guns, but other than that, spare yourself 2 hours and just see the trailer.

Case #2: 2 Fast 2 Furious.
Yeah, M. and I saw it yesterday. And yes, everything is contained in the trailer. Except for the very last scene. The movie was passable, but there was entirely too little gratuitous nudity. But that is the price you pay to turn a movie like that into a PG-13 actioner.

Case #3: Seabiscuit.
Okay, I haven't seen the movie (because it isn't out), but I bet I have seen the whole thing. The set-up of the three men (fallen fighter, fallen corporate titan, the grizzled horse trainer), the horse, etc. The worst part of this trailer is when Chris Cooper says "You don't throw a whole life away just because he's banged up." And then, Hurt says the exact same line later. Argh! Analogy! We get it!

"Don't stop boy, don't ever stop!" Yeah. Please do stop.
