My top 5 would all be from Star Wars.
I picked the best moment from Star Wars and chose 4 from other movies.
1) Star Wars ep. 6: Luke vs. Vader vs. Sidious
2) Planet of the Apes (68 ver): The finding of the Statue of Liberty
3) Alien/Aliens: Ripleys last fight with the Alien
4) E.T.: E.T. waking up from the dead
5) Terminator: The hunting in the factory (end of the movie).
1) Starscream takes down a fleet of jets
-Transformers
2) The failed Robocop scene when one rips its own head off and the other kills the two scientists then himself
-Robocop (Can't remember which, I think it was 2)
3) When the liquid Terminator reformed after getting frozen
-Terminator 2
4) Chestbuster scene
-Alien
5) General Grievous revealing his four arms
-Star Wars Episode 3: Revenge of the Sith
The scene in Aliens when the Marines are forced to surrender their ammunition when under the reactor. The Aliens are agitated and begin to slaughter the marines and the bag containing the ammo explodes. Vasquez and drake reveal their hidden clips and open fire, "lets ROCK!!"
I have to agree with dean martin on the T-rex scene in jurassic park, that was and always will be aces
Murphy gets dismembered by shotguns and assualt rifles in the directors cut of Robocop.
1) POTA 1968 - The Hunt
2) 2001 - the last 20 mins
3) as much as i dislike 99% of THE PHANTOM MENACE ill go for the bit where the hangar doors open to reveal Darth Maul and Duel of the Fates theme kicks in...goosbumps time
4) Tom Bakers Doctor Who agonizing over whether to avert the creation of the Daleks
5) The introduction of Darth Vader in STAR WARS IV - A NEW HOPE
1 Taylor (Charlton Heston) finding out what is at the heart of the Forbidden Zone in Planet of the Apes
2 The first appearance of the Shadow vessels in Babylon 5
3 Charlton Heston (again!) learning from his dying friend what Soylent Green really is
4 The final scene of John Carpenters The Thing
5Asuka Langley Soryu dying to the strains of Beethoven's Ode to Joy in Neon Genesis Evangelion
I'm going to include two moments in my number one spot because you can't mention one without the other.
1) When Batty saves Deckard from falling and says "Kinship" in Blade Runner and Batty's death speech.
2) The "Dogtown" scene in John Carpenter's The Thing
3) The opening scene in Star Wars: A New Hope
4) Chestburster scene in Alien
5) Children of Men, the 4 minute trackshot in the woods
My top sci-fi/fantasty moments:
Vader, in silhouette, ignites his lightsabre in the Carbon Freezing Chamber on Bespin
When Burgess Meredith breaks his glasses in Time Enought at Last.
The pan-shot/montage of Neo-Tokyo in Akira. The soundtrack really makes that scene. (The whole movie really. Despite it being dreadfully confusing unless you've read the comics)
Richard Dryfus looking back one last time before he boards the ship, in Close Encounters
When the Skeksis and Mystics recombine in The Dark Crystal
Kirk/Picard's opening monolouge in any episode of Star Trek
