Marcella Evaristi is a Scottish playwright, actor, and screenwriter. Born in Glasgow with a Scottish-Italian background, Marcella was educated at Notre Dame High School for Girls and the University of Glasgow. Her first play was a monologue called Dorothy and the Bitch (1976), which she performed herself on stage (as were many of her later works). Her writing draws heavily on her own experiences, and often contains witty observations on life from a feminist point of view.

Between 1976 and 1992 she produced eleven plays for stage, and five for radio. BBC Television's 'Play for Today' series included her Eve Set the Balls of Corruption Rolling (1982), in which six former Catholic-educated old friends reunite for the first time in twelve years to swap tales of misadventure. Hard to Get, described as “a critique of feminism”, was televised by Granada Television in 1983, having previously been produced on stage in 1980 and on radio in 1981. Her other works include Commedia (1982), The Works (1984), and The Offski Variations (1990), and Marcella also worked for a time at the University of Strathclyde as Creative Writing Fellow. She recently unveiled her first new work for a number of years, a one-woman play entitled This Time I Promise, which debuted at the Oran Mor, Glasgow in March 2007.
