I've never seen Fight Club before, but over the years EoFF has completely spoiled every twist and turn in its plot, apparently. I probably don't need to bother now.

I like a good plot twist. Whether foreshadowed or not, a radical change can really come as a surprise, especially when you're expecting a particular twist but it turns out completely differently. Video games are good at this (FFVII, FFX and MGS1 and 2, Syphon Filter 1 and 2 in particular).

Some of my favourite 'foreshadowing' is in The Harvard Lampoon's masterpiece Bored of the Rings. It's not exactly subtle:
"Is there no hope?" gasped Frito. "Is nowhere safe?"

"Who can know?" said Goodgulf, and a shadow seemed to pass over his face. "I would say more," he said, "but a shadow seems to have passed over my face," and with that he fell strangely silent.

Frito began to weep, and Stomper leaned forward, and putting his hand reassuringly on Frito's shoulder, said "Fear not, dear boggie, I will be with you all the way, no matter what may befall."

"Same here," said Spam, and fell asleep.

"Us too," said Moxie and Pepsi, yawning.

Frito remained inconsolable...
Then there's alle the foreshadowing of the death of Bromosel, the pointy-shoed warrior of Twodor:
"We cannot stay here," said Arrowroot.

"No," agreed Bromosel, looking across the gray surface of the page to the thick half of the book still in the reader's right hand. "We have a long way to go."
Earlier in the story, Bromosel recounts an ominous dream in which he is told that he will "cash his chips in at page 88".

It comes as little surprise when he ultimately trips over and impales himself on his shoes after his company surrenders to a Narc ambush.
