Including the majestic møøse
A Møøse once bit my sister …
No realli! She was Karving her initials on the møøse
with the sharpened end of an interspace tøøthbrush given
her by Svenge - her brother-in-law - an Oslo dentist and
star of many Norwegian møvies…
Surely it must be the three way gunfight between, Eastwood, Wallach and Van Cleef in The Good, the Bad and the Ugly. The build up and tension as the three antagonist stare at each other waiting for someone to draw. And then suddenly “POW”. It’s over in a second. I love that scene.
Best no gravity scene: Opening credits of Barbarella. Jane Fonda was hot back then.
The best first introduction to your Daddy: **Star Wars Empire Strikes Back. ** “Luke, I’m your Daddy”.
Best hanging on the cross scene: Monty Python’s, The Life of Brian. “Always look on the bright side of life!” Whistle…
The best stoning scene: Also Life of Brian. “Right! Who threw that?”
And the best use of irony: Again Life of Brian. Brian addressing the crowd.
Brian: “You are all individuals!”
Crowd: “Yes, we are all individuals!”
One voice out of the crowd: “I’m not.”
I’m going to have to go with Stephen Root in Dodgeball for that one.
bam!
goggily gets up, waves
“I’m Oka-” BAM!

Alright, I’ll be serious even if no one else is.
you kids…!
best gunfight - Heat (choreographed by ex-SAS uber-bloke Andy McNab I think)
Courtroom scene - JFK (yes, bollocks but very well executed bollocks)

Aw common, what about The Chase? 
You know there are 7, count’em 7 films entitled The Chase? I assume you are talking about the Charlie Sheen one?
