#4 – “I’ll be back.” – Arnold Schwarzenegger, The Terminator (1984)
A three word quote that is instantly recognisable around the world. This line is said by Schwarzenegger’s cyborg assassin character as he is refused entry to a police station which houses his assassination target Sarah Connor. True to his word, he returns by driving a powerful car through the doors of the station before butchering seventeen police officers. Unfortunately for the officers, he was a man of his word.
