Television and stage actress Sally Dexter first won significant acclaim in 1986 for her performance as seamstress Christine in the first theater production of Tom Stoppard's romantic drama "Dalliance". A trained singer, Dexter's musical theater experiences notably include the part of abused girlfriend Nancy in a 1994 revival of the Charles Dickens adaptation "Oliver!" and playing inspirational ballet teacher Mrs. Wilkinson in Elton John's take on the movie "Billy Elliot". Three years after "Oliver!" came another important performance as photographer Anna in the first production of Patrick Marber's caustic relationship drama "Closer". A year after her first television appearance in 1992, she played Hermine, the sister of noted Austrian philospher Ludwig Wittgenstein in Derek Jarman's arty biopic "Wittgenstein". In 1994, she had her first memorable small-screen character as policewoman Maureen Lawson on the crime series "A Touch of Frost", a part she would reprise twice over the next decade. Perhaps her most memorable television role came from 2001 to 2003 on the cult soap opera "Night & Day" as Natalie Harper, a doctor whose life starts falling apart after her daughter mysteriously disappears. In 2011, she expanded her resume by co-writing, along with Jodi Reynolds, the miniseries "Sugartown", a comic drama about a town in northern England that revives its sugar factory.
