Indiana Jones and the Last Crusade 

Harrison Ford’s portrayal of everyone’s favorite heroic archeologist in the Indiana Jones franchise became one of the most popular trilogies of the 1980s, with its final film being Indiana Jones and the Last Crusade.  

When Indiana, played by Harrison Ford, and his father, Henry, played by Sean Connery, are captured at one point, Indiana asks his father how he knew Elsa, who double-crossed them, was a Nazi. He wasn’t supposed to answer in the script, but Connery decided to ad-lib, “She talks in her sleep.” The line and innuendo were golden, and the whole crew loved it.
