C. A. Lejeune's film reviews have long been compared to those of Dilys Powell, whose criticism for "The Sunday Times" overlapped for about 21 years with Lejeune's commentary for "The Observer". Unlike Powell, Lejeune became increasingly disillusioned by various trends in films and, shortly after she had expressed her disgust at Michael Powell's film "Peeping Tom", she resigned from "The Observer" following the release of Alfred Hitchcock's "Psycho" in 1960; she walked out of press screenings of both films. Subsequently, she completed Angela Thirkell's unfinished last novel, "Three Score Years and Ten" (1961) and wrote an autobiography, "Thank You for Having Me" (1964).
