I'll be back
Schwarzenegger tried to have the iconic line "I'll be back" changed as he had difficulty pronouncing the word "I'll". He also felt that his robotic character would not speak in contractions and that the Terminator would be more declarative. Cameron refused to change the line to "I will be back", so Schwarzenegger worked to say the line as written the best he could. He would later say the line in numerous films throughout his career.
