So, if you could watch any one scene be filmed...

[Blitzkrieg Bop]

...in person, what would it be? You'd be there on set, off to the side, watching the scene be filmed in its entirety.

I'd choose Travis' "You talkin' to me?" scene from Taxi Driver. It's one of the most iconic moments in the history of film and De Niro pretty much made the whole thing up on the spot. Not only would I watch De Niro, but whoever else was on set that day, looking at their reactions.

_ Robert Mitchum's right hand/left hand speech in Night of the Hunter.
_ The opening scene in the Korova Milk Bar in Clockwork Orange.
_ The "Blood test" scene in The Thing.
_ The precinct scene between the Joker and Batman in TDK.
_ "Do you think I'm funny?" in Goodfellas
_ Quint's monologue in Jaws.

and many many more

Timothy Treadwell most likely trying to touch up and hug a bear before being nomnomnomnom.

He didn't die on screen.


Personally, I'd say none. I think it'd ruin the magic of the moment to see the various takes and screw ups and all that stuff.

 

[Why Are You Crouching Spock?]

He didn't die on screen.

Actually it was filmed. It was only the audio that could be heard as it was covered by the tent.
Which is apparently horrific. You also hear his girl-freind running around playing tig before yogi gets her too.
