It's always difficult start new threads here because there are always systemic trolls like Muck Ficon who ruin them but I am going to take a chance here. It's one of the flaws of this site in not having moderators to euthanize these trolling posters.
Crowe Diddly had an interesting take on the new Mission Impossible thread, in that while the action was great, the movie lacked any interesting themes or emotional attachments. I agree, as much as I liked the movie I basically forgot about it the next day.
So that got me thinking about the movies I remember many years after I saw them. The movies that stuck with me even though I have not seen them for over 10 and in some cases nearly 20 years. In other words, when I am driving in my car the movie just pops in my head. I am not using clips below, it makes the thread too long.
1) The Godfather: I don't know why, but when the Turk meets Vito Corleone (Brando) for the first time and they sit down, Vito pours a wine for the Turk and a little wine drips on his pant leg and Vito brushes it off. Great scene
2) The Sixth Sense: The ending. I remember seeing this in the theater and I was absolutely blown away. I have not seen it since, what 20 years? Still resonates all these years later
3) Saving Private Ryan: The opening scene, just too much to process, unreal
4) Apocalypse Now: The scene where the CIA agent says to Martin Sheen : 'Terminate with Extreme Prejudice'
5) End of Red Dawn where Patrick Swayze is carrying his dead brother (Charlie Sheen)
I think about these movie scenes all the time. Add to the list as you see fit.
