I'm Batman

one of the best movie lines is

" Nigga, you ain't no Pimp. You a rest-haven for Ho's " Pretty Tony

from 'The MACK'

there are sooooooooooooooooo many others, but their not 'one liners'

"The first casualty of war is innocence."

"There are 3.7 trillion fish in the ocean. They're looking for one."

"A long time ago in a galaxy far, far away...."

"In the future, cities will become deserts, roads will become battlefields and the hope of mankind will appear as a stranger."

" Only one man can make the differance"

"Ruthless... Savage... Spectacular"

"When all that's left is one last chance, pray that he's still out there ... somewhere!"

(these four above are all from the same movie)

...and of course this one,although technically it´s not really a tagline :

"A Philadelphia fighter who never made the big time...He showed he could take on a challenge...and won something bigger than a championship bout."

"When there's no more room in hell, the dead will walk the earth"

"Just when you thought it was safe to go back into the water."

That's not a tagline though, IMO

It's a legendary couplet from the The Ring Trilogy.

(Any excuse though to state it. )

One Ring to rule them all,

One Ring to find them.

One Ring to bring them all

And in the darkness bind them.
