Crisp was the subject of the play "Resident Alien", by Tim Fountain, which starred his friend Bette Bourne in 1999. The play opened at the Bush Theatre in London and transferred to the New York Theatre Workshop in 2001 where it won two Obies (for performance and design). It went on to win a Herald Angel (Best actor) at the Edinburgh Festival in 2002; subsequent productions have been seen across the US and Australia. A film of the same name was released by Greycat Films in 1990.
