What?
Yea imma need a bit of explanation on this one, this feels like AI just posting random shite
Back To The Future, where Marty McFly calls himself Darth Vader in front of his terrified father, while pretending to be an alien.
Oooh, ok, that’s hilarious. Forgot about that.
Yep! Sounds like it’s time for a rewatch!
It was at least partially a deleted scene actually? I’m not sure anymore either… www.youtube.com/watch?v=BaYADHcpdng

The part that was actually in the released movie ends at 0:45. (You can also tell by the fact that the audio/video very obviously changes to daily footage at that point.)

If you can’t quote every line from memory, clearly you need to watch the whole trilogy again.

That is a fair argument.

Whaaat!? I have no recollection of this! Was this is in the final cut?
This is how the scene was in the final cut: www.youtube.com/watch?v=hHZctSnNrsw

And then there’s a follow-up scene the next day, where George tells “Calvin Klein” about the encounter.

Having George retell it worked way better than showing it directly, IMO.

George Mcfly freaking out about his visit from Darth Vader

Agreed, but without showing it, it would be extremely confusing to the audience. After watching the extended scene, it would have been really bad if they left that all in. Plus the scene is funny with the eddie van halen tape, and also uses the contents of Doc’s luggage with the hair dryer for another gag.
This one took me a minute. The actor in the pic played Marty McFly’s dad in Back to the Future. There is a scene in the movie where Marty is trying to scare his young dad, and wakes him up wearing a hazmat suit with face covering, putting headphones over his ears to blast Van Halen and calling himself Darth Vader.

In Back to the Future, Marty uses his father’s love of sci-fi books to scare him by pretending to be an alien called Darth Vader from the planet Vulcan. This meme shows the realisation later when the father watches Star Wars (the father is played by Crispin Glover)

Last night, Darth Vader came down from planet Vulcan, and told me that if I didn’t take Lorraine out, that he’d melt my brain.
