In Resident Evil: Apocalypse, Jill had been a rising star in the S.T.A.R.S. organization, before her reputation was ruined after a botched mission know as "The Arklay Mountains Incident". Information from the movie's website indicates that she gained insight into a "classified bioweapon weakness", which was said to be a "cranial flaw". In the movie Resident Evil: Apocalypse, Jill is portrayed by Sienna Guillory. Early in the film, a newspaper article in her apartment hints at her dismissal from the S.T.A.R.S. unit and her involvement with Nemesis. It also states that Jill was suspended from S.T.A.R.S. after the death of her partner, Leon Kennedy. Both add to similarities between the movie and the game Resident Evil 3: Nemesis. Although, due to the vastly different conclusion, as well as the role of Alice, the game and movie are alternate universes.  [Resident Evil Wikia]
