Your post doesn't stipulate that a clue needs to be spelled out, besides which foreshadowing is not necessary to a plot twist. That's just something you made up and get to move goalposts around. How Kathleen Kennedy relates illustrates the lengths of "made-up" to which you've drawn your spurious connections
No, with every twist in every movie there are clues, or 'foreshadowing.'
That is the difference between surprises and twists.
A plot twist casts a story into entirely new light or direction.
Please explain how this is different than a surprise.
Are they synonyms?
THE TWILIGHT ZONE did this every episode.
I've never seen an episode of Twilight Zone, so I can't give examples of which ones were twists or surprises, or if they were all suprises or all were twists.
TERMINATOR 2: the plot twist is Arnold's the good guy. No hint of that.
Kinda irrelevant because the marketing gave up the 'twist' weeks before its release. But I imagine since the T-1000's introduction was first, and he killed a cop, that have away he was the villain. The T-800 didn't, and the comical choice of the 'Bad To The Bone' track were clues.
But, it wasn't a suprising twist because Arnold had been playing good guys for years.
PLANET OF THE APES: they're on earth the entire time and there was no hint until the very end if you don't count the VHS box cover. (Damn you, you dirty home video marketers).
Haven't seen it.
What you seem to be arguing is something that applies against deus ex machina, where a surprise event occurs without any feasibility in the sense of set-up or foreshadowing. But unless you have something more, what you're talking about isn't on-topic anymore than Kathleen Kennedy.
No. Dues Ex Machina is a totally different topic.
Darth Vader saying "No Luke, I am your father," is not a Dues Ex Machina.
It did not save Luke from certain death or failure.
