what are some of your favorite opening scenes in movie history?

hi all!

just to clarify this doesn't have to be movies that are considered masterpieces (or honestly even movies that are great) - i'm more curious to hear about movies where the first scene just completely hooked you, blew you away and you knew you had to keep watching. can be any genre or from any era and can be your "favorite" opening or an opening that you feel is just really really strong and re-watchable.

for me, i think the opening sequence in Baby Driver is an absolute blast - from the very first moment he plugs in his ipod you knew you were in for a ride and it 100% captured my attention.
