To the Public Danger is a 1948 British drama film directed by Terence Fisher and starring Dermot Walsh, Susan Shaw and Barry Letts.
It was made at Highbury Studios as a second feature for release by the Rank Organisation. Like other Highbury productions, it offered acting opportunities for several of Rank's young contract stars. The film's sets were designed by Don Russell, although a number of the scenes were shot on location.
It was based on a 1939 radio play by the writer Patrick Hamilton, who had been encouraged to write the story as part of a government road safety campaign. Hamilton had himself been knocked down by a drunk driver. The story was updated slightly, and represents the post-war malaise with the use of noirish sequences. After making the film Fisher graduated to directing several more expensive productions for Gainsborough Pictures.
