Kill Bill 1 and 2.
Color Me Kubrick - John Malkovich as a guy who impersonates Stanley Kubrick for fun and profit.
Oh yeah! Being John Malkovich.
Primarily a play, but I’m sure movies have been made of it: The main character in Shakespeare’s Julius Caesar is Brutus, not Caesar.
Arguably, the main character in King Lear is Cordelia, and the main character in The Merchant of Venice is either Shylock or Portia (they’re the only ones who actually do anything).
Kate probably is the lead in The Taming of the Shrew, though, even if Elizabethan audiences wouldn’t have regarded her as such.
I’d say fourth, after Wesley, Inigo, and Fezzik. But she’s probably ahead of Vizzini, Humperdink, and Grandfather, and certainly ahead of Rugen, Miracle Max, and The Albino
The credits list Robin Wright 8th. Wesley, Inigo, Humperdink, Rugen, Vizzini, Fezzik, The Grandson, The Princess, The Grandfather, The Impressive Clergyman. So far from the lead. Wasn’t it her first role?
ETA: Third role
Buttercup’s not a character in that film, she’s a prop.
I love the movie, but it’s not exactly overflowing with strong female characters.
Her credit says “And Introducing”
