The Very Abridged Script
FADE IN:
INT. THE LAKE HOUSE
SANDRA BULLOCK moves out of a HIDEOUS LAKE HOUSE and leaves a letter for the next tenant. KEANU REEVES, 2 years in the past, gets the letter.
KEANU REEVES
(writing back)
Whoa. I think we're in the middle of the movie Frequency, except with a mailbox instead of a radio.
SANDRA BULLOCK
You're living in 2004? Quick, tell me who you're going to vote for.
KEANU REEVES
Bush.
SANDRA BULLOCK
He winds up getting a blowjob from an intern, tell your friends.
They fall in love with each other through time. KEANU REEVES replaces the mailbox with one large enough for him to fit inside, ending the movie.
