|Sarah Polley (1979 - )|
|eXistenZ (1999) [Merle]: Shot several times in the stomach by Jude Law in the church that they're using as a game-testing facility, while Jennifer Jason Leigh simultaneously shoots Don McKellar. (Thanks to Tal)
The Life Before This (1999) [Connie]: Shot in the stomach (off-camera) in the crossfire of a gunfight between David Hewlett and Joel Keller in a cafe. Her body is shown lying behind the counter afterwards. (The movie shows two different outcomes for the incident at the beginning and the end of the film; Sarah only dies in the second version.) (Thanks to Tal)
My Life Without Me (2003) [Ann]: Dies (off-screen) of ovarian cancer. The movie fades to white on a close-up of her face before her death, followed by a sequence of the other characters going about their lives while a tape-recording by Sarah plays as a voiceover.
Dawn of the Dead (2004) [Ana]: Killed (off-screen) by the zombies. The movie ends with video-camera footage of the zombies closing in, interspersed with the closing credits, so her fate is only strongly implied rather than actually confirmed.
John Adams: Peacefield (2008) [Abigail 'Nabby' Adams]: Dies (off-screen) of breast cancer; we last see her speaking to her parents (Paul Giamatti and Laura Linney), followed by a scene of Laura tearfully putting away Sarah's belongings. (Thanks to Stephen)
