Two excellent films, with some impactful dialouge.
But it isn't close. Slience of the Lambs is one of the greatest Thriller / Horror films in history, with one of the most iconic characters in the history of cinema with Hannibal Lecter. A character so strong, that despite being a crazed serial killer, he became a partial protagonist.
SOTL is also the only film in history to sweep all 5 major Academy Awards in one year (Best Picture, Best Actor, Best Actress, Best Director, Best Orig. Screenplay) back in 1990, beating out juggernauts like Goodfellas.
I expect Silence of the Lambs to make an honest run at winning this tournament.
