The opening scene of The Godfather.
The Horsehead scene.
Luca Brasi sleeps with the fishes scene.
The Restaraunt scene with Michael.
The Death of Sonny scene.
The Baptism Scene.
The ending scene when Michael becomes The Godfather.
These are all iconic moments in Hollywood.
Don't forget the scene when Appalonio got killed in Italy. That turned Mike into the cold hearted guy cuz that was his true love not Kay.
Michael, Fredo, and Moe Green in Vegas.
"Fredo, I love you and you're my older brother. but don't ever take sides with anyone against the family again. Ever."
Tessio getting walked off to get killed.
"Tom, can you get me off the hook for old timed sake?"
Carlo having to answer for Sonny.
"Only don't tell me your innocent. Because it insults my intelligence. It makes me very angry"
The scene when Mike and Vito we're talking before his death. Too many classic quotes.
"women and children can be careless, not men."
"I like to drink wine more than I used too"
"I never wanted this for you" "Senator Corleone, Governor Corleone"
"We'll get there pop"
This scene alone is a masterpiece. The Don went from a caring grandfather and father into the Godfather advising his son one last time just as natural as breathing.
