Girl on the Run is a 1958 private detective film directed by Richard L. Bare and starring Efrem Zimbalist Jr., Erin O'Brien, Shepperd Strudwick, Edd Byrnes and Barton MacLane.

O'Brien's singing voice was not dubbed; she appeared as a featured solo singer on six episodes of The Steve Allen Show during this period.

Writer Roy Huggins created the story's characters in a series of 1940s novels and novellas, but Marion Hargrove wrote the screenplay for Girl on the Run.

This allowed Warner Bros. to claim that the resulting 77 Sunset Strip television series was based on Girl on the Run, which it wholly owned, rather than on Huggins' literary work.

At the beginning of the episode that followed Girl on the Run, Zimbalist broke the fourth wall with the announcement:We previewed this show, and because Edd Byrnes was such a hit, we decided that Kookie and his comb had to be in our series.
