Torn Curtain
Waterhouse's first screenplay was the film "Whistle Down the Wind" (1961). Without receiving screen credit, Waterhouse and Hall extensively rewrote the original script for Alfred Hitchcock's "Torn Curtain" (1966). Waterhouse wrote the comic play, "Jeffrey Bernard is Unwell" (1989; Old Vic premiere, 1999), based on the louche life of London journalist Jeffrey Bernard.
