Actress Sienna Guillory appeared in flick Resident Evil: Apocalypse as character Jill Valentine, but was M.I.A. in the third film, Resident Evil: Extinction. rumours have it that there was a contract dispute with the actress.
Director Paul W.S. Anderson is currently filming Resident Evil: Afterlife and star Milla Jovovich tweeted this tidbit: "Valentine MAY be back." That also means she may not be back.
Perhaps, Guillory worked out her contract issues or perhaps the producers are bringing on another actress altogether to play Valentine.
