David Warrilow (Stone, December 28, 1934 – Paris, August 17, 1995) was a British actor, considered one of the foremost interpreters of the works of Samuel Beckett. A founding member of the New York-based experimental theater company Mabou Mines, he developed a close collaboration with the Irish playwright, who wrote the monologue *A Piece of Monologue* (1979) specifically for him. His career is inextricably linked to memorable productions of Beckett's texts, notable among which are *Krapp's Last Tape*, the premiere of *That Time*, and pioneering television works such as *Eh Joe*. In addition to the stage, Warrilow appeared in several films, playing character roles in works such as the Coen brothers' *Barton Fink*, Martin Scorsese's *The Last Temptation of Christ*, and Woody Allen's *Radio Days*. His exceptional interpretive rigor and his contribution to avant-garde theater earned him numerous accolades, including several Obie Awards, one of which was for Sustained Excellence in Performance.
