"The Fifth Element" (1997)
In this oddball sci-fi flick full of otherworldly characters (including an opera-singing blue alien), Willis is a grounding force as cab driver Korben Dallas. His life turns upside down when he learns he has to protect the Fifth Element, better known as scantily clad heroine Leeloo (Milla Jovovich). Of course, Dallas is more than your ordinary cabbie. He’s a former major in the Special Forces, perfectly equipped to defend this orange-haired beauty from the evil Zorg (Gary Oldman). Silly? Yes. Fun? Definitely.
