Those films were eligible for Best Picture but for for some reason weren't nominated. It's funny how The Sweet Hereafter could be nominated for Best Directing and Best Screenplay but not be nominated for Best Picture. Only three of the five Best Picture nominees that year (As Good As it Gets, The Fully Monty, Good Will Hunting, L.A. Confidential, and Titanic), received nominations for both writing and directing (The Full Monty, Good Will Hunting, and L.A. Confidential).
