There can be only one!
And it’s not Highlander…it’s Alien.
This trailer should be THE template for all other trailers. It’s more effective than most films. But it’s main strength is that the film is depicted extremely well and yet you know nothing about it! You know it’s going to terrifying but you don’t have a clue about what will happen.
Contrast with the worst trailer of modern times: Spider-Man 2. You are told exactly what will happen. So lame.
I had to say modern times because old trailers used to basically do what the SM2 trailer did: tell you the whole story. But that’s rare nowadays.
