7) E.T. the Extra-Terrestrial (1982)
The memorable final scene of Steven Spielberg's 1982 family classic is enough to leave even the most cold-hearted of viewers in tears, and sees a sobbing Elliott sending his alien best friend on his way back to his home planet. E.T. touching Elliott's head with his glowing finger before his croaky voice intones "I'll be right here" gets us every time.
