Capote's adaptation of Caspary's Laura, 1968.

The Paley Center for Media remembers the TV adaptation of Vera Caspary's Laura, which debuted today in 1968. Scripted by Truman Capote, it starred Capote friend Lee Radziwill (as Laura Hunt), Arlene Francis (as Ann Treadwell), Farley Granger (as Shelby Carpenter), Robert Stack (as Mark McPherson), and George Sanders (as Waldo Lydecker). Reviews were not that kind (see this example from the Milwaukee Journal).

Happy birthday, Michael Arlen.

Michael Arlen—best known for The Green Hat (1924) and the series of films featuring the Robin Hood figure The Falcon (with George Sanders and his brother, Tom Conway)—was born today in Bulgaria in 1895. Several of his works involve murder and crime, especially those with Michael Wagstaffe. Hell! Said the Duchess (1934) features a supernatural being framing the duchess of the title for murder. The Alfred Hitchcock Presents episode "The Gentleman from America," in which a man bets that he can stay in a room that reputedly is haunted, is based on an Arlen short story from The Omnibus of Crime (ed. Dorothy L. Sayers, 1929). Arlen's son, former New Yorker writer Michael J. Arlen, discusses his father in Exiles (1970).
