We could be quoting great movie lines in our everyday conservations without even realizing it — that’s how popular some of the best lines of all time can become.

Screenwriters put their blood, sweat and tears into their work, hoping that a line, a theme, an idea, an expression forever sticks with people and rises above a mere piece of dialogue — while actors pour their hearts and souls into their work as well, hoping to become part of an unforgettable moment.

Maybe a line expresses a truth or a feeling we’ve all struggled to put into words ourselves.

Or perhaps it lands at the perfect moment in time — and helps give audiences the spine-tingling excitement that only the very best films provide.

No matter the reasons, exceptional movie lines will forever live in our pop culture. Check out the gallery below to see 30 of the best. And if you think we’ve missed any, let us know in the comments section below!
