Young Man SPOILERS
I posted this a long time ago, and thought I would re-post it since the older one got deleted. If you've seen the movie just once, and wanna watch it again, and didn't expect what was going to happen at the end, here's some clues you should look for when watching it again
1. David constantly snaps at Alexis to watch the road, and honks his horn, like he's signalling for the Young Man to pretend to fall and be hurt
2. While on the ferry, David goes to get a cup of coffee, and the Young Man walks into the coffee area at the exact same time David exits
3. The surprise picnic and going on the boat, and ending up on the island, where the Young Man happened to be. When David walks off into the fog, the Young Man comes out
4. David quickly moves away from the Young Man, after patching him up, when Alexis brings more firewood
5. David is the one who brings the Young Man a blanket during the night
6. Young Man knows exactly what David likes in his coffee, but has to ask Alexis what she likes
7. David quickly moves away from Young Man in the kitchen, when Alexis comes walking in
8. David brings home two lobsters instead of three, thinking it would just be him and the Young Man for dinner, and stops surprised in the doorway when he sees Lex is still alive, and blames it on eating bad clams, then quickly recovers
9. The boat just happens to die when they're on their way off
10. When Alexis asks Young Man if he's ever been in love, he says no, and looks right at David
11. Also, before going to play golf he begs Alexis to not forget the mushrooms
There's more, but that's all I got right now
