 This film, which established Peter Falk (I) (qv) as the definitive  Lt. Columbo, was adapted from a 1962 play by the same authors, which  had starred Thomas Mitchell (I) (qv) as Columbo. This in turn had  been adapted from the _"Chevy Mystery Show, The" (1960)_ (qv)  episode "Enough Rope", in which Bert Freed (qv) originated the  role of Columbo.
