So many.....
"I'm Spartacus" from Spartacus
"Luke, I am your father" from Star Wars: Empire Strikes Back
Mufasa snuffs it from The Lion King
There are so many, my brain is racing to fast to pick more!
While I'm not the most rabid fan of Jack Nicholson, he totally shit-kicked me in that scene near the end of "Five Easy Pieces", where he tries to make peace with his long-estranged, mute father, played by Will Geer. The way Nicholson SO GRADUALLY breaks down puts a lump in my throat. That is my definition of acting.
Also reminds me of Sally Field at the end of "Sybil" where she repeatedly yells "I hate her!" upon realising the main wellspring of her troubles - her mother. The primal intensity of it was absolutely galvanizing.
The opening tracking shots in "The Player", "Touch of Evil", and "Boogie Nights", and the ones in "Goodfellas" and "Weekend". Those are scenes, aren't they? Can't remember the Max Ophuls film that had a nifty tracking shot of a waiter holding aloft a tray and zipping through a crowd.
in "The Straight Story", Richard Farnsworth around a fire at night, telling a hitchhiker about his take on family.
the "Is it safe?" dentistry hijinks in "Marathon Man"
the bowling alley scene in ""There Will be Blood"
Peter Finch's "I'm mad as hell" rant in "Network"
the opening shot in Polanski's "MacBeth" of the endless tidal flat, as a stick enters the frame from (I think) top right - the witchy-poo's stick!
Ellen Burstyn and Kris Kristofferson's big argument in the restaurant near the end of "Alice Doesn't Live Here".
couldn't find youtube links for the following two TD descriptions, so if you can indulge these long descriptions......
two scenes from "Tin Drum".........where Agnes sits down to dinner with her husband, whom she had just screwed around on with his brother - barely moments before the meal. And the meal itself - EELS! She insists on having a good helping, despite her previous vomiting repulsion to them, and, to her husband's and housekeeper's astonishment, proceeds to absolutely maow down on them, with the most unforgettable, unblinking, staring-straight-ahead look of........losing it? which was indeed the case, totally going kookoo, and the look in her eyes is one that is so intensely in some far away land. Her skin has the most ghostly white pallor (great lighting!). She doesn't say a word. Basically - one heavy fucking meal. Dear lord I hope she didn't have to do too many takes!
The other scene from TD is earlier on, where Agnes hooks up with her brother-in-law in a hotel room. She enters the room and closes the door behind her. Buddy's already at the bed. For a second they just look at each other, and then begin to disrobe, maintaining their substantial distance from one another. I love the way they gradually increase the speed of their stripping - those pesky, time-consuming buttons that the two of them are too methodically German to just tear right off. They lock eyes during this seething-with-volcanic-lust strip show, and to contrast this animal ferocity with the distance they keep between themselves makes for a tension that is almost palpable. You're on the edge of your seat, and like, "ok! get it on, you two!" and when they finally DO get down to business, Oscar, her uber-brat of a son, spies on them from a clock tower, across the street from their window, and does that annoying scream, pointing like the Family Guy monkey.
Welles clumsily groping at shit in the bedroom-destroying scene near the end of "Citizen Kane". Let's hope not too many takes for that one either.
the only scene I remember from "True Romance" where Hopper lectures Walken about his Moor roots.
in "Magnolia" - Frank Mackey's interview, and the frog storm. And any Reilly/Walters scenes.
any food-eating scene in "Frenzy". Also that creepy, silent, up the stairs/back down the stairs tracking shot at Rusk's place.
Bill Pullman talking to the eyebrowless Robert Blake in the party in "Lost Highway".
King Arthur's sword fight vs. the Black Knight in ".....Holy Grail"
