I went to a comic convention in Bristol and there was a screening of the Judge Dredd film starring Sylvester Stallone.
The presenter/host of the screening was Alan Bishop, the editor of 2000AD.
For three hours the man just ripped the **** out of the film. It was brilliant. He'd pause it and yell.
There was one scene:
Hershey: "Look Dredd, I have friends, I have a social life."
Bishop paused the film.
Bishop: "I invented the character. No she doesn't."
Then hit play.
After a while, the audience started getting in on it, and there's a scene where Judge Dredd has a gun pointed at the villain Rico who has Hershey held hostage: the big ABC mecha warrior is holding Hershey by the head. Then evil Judge Rico says, "Robot, on the count of three crush her head! 1... 2..." and Dredd drops his gun and surrenders.
Someone yelled, "WHY DOESN'T HE JUST SHOOT RICO THEN HE CAN'T SAY 'THREE'?!?!?!?!?!"
Another great moment was in the climax, before the sequence began, Bishop paused the film and said, "Watch. The explosion starts for no reason." Ten-fifteen minutes later, the explosion happens and the audience remembers what he said, and how we all laughed.
I remember seeing the Two Towers trailer in the cinemas and we all already knew Gandalf came back and in the trailer, at the end of the trailer Gandalf 'returns'. A friend of mine, quite mockingly, yelled "WHAT?!?! BUT HE'S DEAD!!!"
But the most recent example was me:
We went to see Rocky Balboa and in the trailers there was a trailer for a film that played the Requiem for a Dream music as it's 'hook' went across the screen.
EVERY SECOND...
A SUN EXPLODES...
IN 2007...
IT WILL BE OURS...
Immediately I began laughing loudly and hysterically, only increasing with laughter as the plot of the film seems to revolve around a crack team's attempt to REIGNITE the sun with a bomb. (!!!)
Then, one character in the trailer says, I kid you not:
"If the sun dies - we all die."
I laughed even louder.
Then I fell to the floor, crying and howling with laughter when the title of the film was displayed:
SUNSHINE
