off the top of my head the ones i think of are the intro to X2, with nightcrawler teleportating through the white house and the intro of the matrix, with trinity escaping the agents
Tragically, not the entire beginning...but enough to give you a good idea of the start of this great film.
The Jack Elam bit with the fly is great in itself, but the very sparse dialog rules. "Looks like you bought two too many.
Around the same time, we had the great opening sequence of The Wild Bunch (for which I could not find a satisfactory clip). "If any of them move...kill them!"
Crap movie but the opener is one of the coolest....Probably the only reason I'd watch the movie....X-men Wolverine Origins....The war montage where he and victor are fighting in all the major wars....Can't link it, its all fooking video game footage on the tube.
