If it's crap ... We'll tell you
For this topic i think of the ways that movies have started that grabbed your attention or set the mood or just started differently from a lot of other things.
Lord of War began the entire movie out really different by showing the life of a bullet being made and entering a body, that holds anybody's attention or shocks as well.
Watchment-explaining the superheroes and going through America's history was cool in a warped way, like the Lesbian Nurse kiss after WWII was over was a nice touch and Bob Dylan music playing throughout the whole thing.
Every "Pirate" movie beginning with Jack Sparrow has a fun start to them. When he shoots the bird from inside the coffin was fun to watch. As well as in the first when his boat sinks.
The Walking Dead starts out shocking with the Police chase and quick to Zombies.
Nearly every one of the James Bond movies always had fun starts.
Any more ideas?
I would have to say that one of the best movie openings of all time was that of The Lion King, the way that huge sunrise first hit the screen at the start of The Circle of Life just gave me the chills
Ginger Snaps hands down
The Dark Knight, The Town, Inception, Office Space, The Pilot of LOST, and Pulp Fiction all have great first scenes.
This was a test.
You have all failed.
Wrong again! The winner is clearly Touch of Evil
The opening credits of The Watchmen was the best thing about the whole film.
Which isn't saying much.
