We love Firth, but the real male MVP of Austen adaptations is Jonny Lee Miller. The actor made his Austen debut in 1999's Mansfield Park where he plays the charming Edward — the only person in the wealthy Bertram household that truly understands Fanny. Miller is a big part of why the movie is endlessly rewatchable, but its the liberties that director Patricia Rozema takes with the story that makes this version a classic.
Rozema includes a subplot that tackles the Bertram family's involvement in slave trading, and includes elements from Austen's own life to create an adaptation of Mansfield Park that isn't afraid to incorporate the more difficult elements of the era into the story.
