What is your favourite scene from a David Lynch movie or TV show?

Mine, in terms of sheer emotional power has to be Sherilyn Fenn's from Wild at Heart. But I'm sure I could be persuaded by your posts. Other great scenes are from TP when Sarah realises Laura's dead in the Pilot and Maddy's death in Episode 16. (Tells you something about the director when all your favourite scenes involve death)

The "one bad car accident" from Wild at Heart

The "Hollywood Boulevard" sequence from Inland Empire

Ben's place in Blue Velvet

John Merrick visits with the Treves'

Alvin Straight shares memories with a fellow veteran

"This Magic Moment" from Lost Highway

"Club Silencio" from Muholland Drive 

"Every day holds a new beginning and every hour holds the promise of an Invitation to Love." 

Alice's seduction of Pete (Hollywood Sunset) in LH

Nikki shoots the Phantom in IE

Club Silencio in MD

Dean Stockwell singing "In Dreams" from Blue Velvet.

I like the first Winkie's scenes from Mulholland dr. too. Something really spooky about the acting.

All of Eraserhead and Fire Walk with Me (I can't choose between all the good scenes). 

"What credit card do you want to put that on?"
"Caash, prease."

 That winkie's scene is intense!

Another scene that is a hightlight for me is the beginning of season 2 of TP. When that senile hotel - employee visits cooper when he's shot. That is just some other - wordly whatchamacallit!

This is a sentence and you are reading it now.

Club Silencio

Crazy asain girl towards the end of inland empire 

Maddy being killed in twin peaks

Laura being killed in FWWM

The meeting about who will be the lead actress in MD (the part with the espresso)

The "I Told Every Little Star" scene from MD

The Cowboy and the whole lead up to the Cowboy MD

2nd episode (i believe) where cooper first has the dream of the red room

Frank singing "in dreams" (I believe that's what it was called or candy colored clown or whatever) before beating up Jeffery. 

B.V. - Ben's Place

W.H - Failed bank heist; the dog running off with the hand kills me every time

L.H. - Mr. Eddie's drive in the country.

M.D. - Club Silencio

FWWM - Laura's visit to Harold Smith; The Hap's diner scene; and waking up Carl (friggin priceless)

Fred Madison sitting and smoking the hell out of a cigarette, the buzzer and the message.

Alvin Straight sitting at the bar, talking about the war.

The Cowboy talking to Adam Kesher in the lot at night.

The murder of Maddie vs Cooper at the Roadhouse.

The live on-the-air sketch completely falls apart, with the camera on its side and everyone at home laughing.

"Every day holds a new beginning and every hour holds the promise of an Invitation to Love." 

"In Dreams" from Blue Velvet...then the 'Pretty Pretty' scene with Frank about to beat Jeffrey up...that chick dancing on the car as the music plays...

Mr. Eddie car chase scene in Lost Highway--I don't think I laughed harder at anything than I did at that. LOL 

Sherylin's scene in Wild at Heart.

Twin Peaks: Fire Walk With Me--the scene of Laura crying in the Roadhouse, the scene with Laura and Donna laying in the living room... "...and the angels wouldn't help you...because they've all gone away", Carl's scene getting woken up BEFORE 9,  "Goodnight, princess" scene between Leland and Laura, very ending with Laura, Coop, and the angel.

Twin Peaks: Discovery of Laura, Coop's drive into town, The World Spins/Maddy's death in 14, Leland/Bob being unmasked/Leland dying in Coop's arms, and every scene in episode 29. :)

I've been known to pop the DVDs of either LH or MD into the player, just to quickly watch either the "this magic moment" or "Winkies" scenes.

Another one I go back to a lot is "it wasn't you, but it looked like you" from LH. The way the camera moves around Pullman in that scene.....the whole thing is just sublime, IMO....

Wild at Heart: Juana's murder of Johnnie Farragut.

Twin Peaks: Leland and Sarah are informed of Laura's death (Pilot).

Inland Empire: Nikki's first encounter with the prostitutes ("Ghost of Love").

FWWM: The Phillip Jeffries/Lodge inhabitants scene.

If "Favourite Lynch Scene" were meant as my favorite with Lynch acting in front of the camera, then I'd have to say his scene in Twin Peaks kissing Shelly. The way Coop starts to say, "Uhh, Gordon..." along with the stunned look on Bobby's face while Cole goes in for kiss #2 were priceless, while Cole is blissfully unaware of the awkwardness he was creating, as usual. That's a nice breed of magic.

If "Favourite Lynch Scene" means anything he's directed, that's been covered very well by the other fans here. I find myself agreeing with everyone.

My favourite scenes are:

1) Spencer's rolling head in Eraserhead (Surreality! Pure ART!)

2) the crazy final run with the car escaping from the Unknown while David Bowie sings "I'm deranged" in Lost Highways (Fatality! An inner mortal kombat in the character that grows inside the head of the spectator as a primal scream while the yellow stripes run off)

3) The lesbian kiss in Mudholland Drive: I ADORE those women! (Lesbiality! The beautiest way of kissing someone as a form of pure passion and art)

And everything from The Elephant Man, of course....A true TOTAL masterpiece in which you cannot divide a scene from the other (Cinemality! TOTAL CINEMA ITSELF!)

if it has to be one then...

FWWM

the scene from Laura outside 'the bang-bang' and the 'log lady' touching her forehead...which leads to the triumvate of tunes 'Questions in a World' 'The Pink Room' & 'Blue Frank' has become my favourite Lynch scene/piece of all time (even topping Blue Velvet's In Dreams scene).  Its just the greatest collage of sound and images that I've ever had the pleasure to witness...yes the subject matter is dark & heavy (no shit, its Lynch afterall) but the overall effect is visually and sonically breathtaking.  The contrast between the heavenly Cruise tune which segues into the Lynch penned Pink Room/Blue Frank 'bang-bang' hellishness...is pure genius (although I'm loathe to use that term generally).  To conclude, this scene is both incredible & horrible, yet still chaotically beautiful...it ends with a sublime crossfade from the dirtiest bar floor to the wind in the trees in Twin Peaks.  15+ mins of jaw dropping artistic intensity.

Overall, it could easily be the gorgeous ending to Fire Walk With Me. The music is just so perfect and fits the mood, along with Sheryl Lee's acting and the way it closed the whole Twin Peaks saga. As for his other stuff:

Eraserhead: beginning with Jack Nance's character walking to his apartment.

The Elephant Man: train station scene.

Blue Velvet: "Don't be a good neighbor to her" scene

Wild at Heart: bank robbery, opening scene or "Love Me" number

Lost Highway: when Pete stands up and it's actually Fred again, with an eerie sound effect playing in the background

Mulholland Dr.: "I've Told Every Little Star" scene

Inland Empire: "Locomotion" scene

The Lost Highway scenes in Lost Highway.

Then the FBI scene with Jeffries in Fire Walk with Me.

Then the Tremond picture scene in Fire Walk with Me.

Then Rabbits. Probably.

Eh, all are almost the same kind of scenes. I like it when we go "beyond".

first half of FWWM - mind blowing.
