Dangerous Corner is a 1932 British play by the English writer J. B. Priestley, the first of his "Time Plays". It was premiered in May 1932 by Tyrone Guthrie at the Lyric Theatre, London, and filmed in 1934 by Phil Rosen.
Priestley had recently collaborated with Edward Knoblock on The Good Companions and now wished "to prove that a man might produce long novels and yet be able to write effectively, using the strictest economy, for the stage." While it was praised highly by James Agate, Dangerous Corner received extremely poor reviews and after three days he was told that the play would be taken off, a fate that he averted by buying out the syndicate. It then ran for six months. Priestley's action was further vindicated by the worldwide success the play was to enjoy, although he soon lowered his estimate of this work and as early as 1938 remarked "It is pretty thin stuff when all is said and done."[1]
