* You might be thinking of the 1942 film "This Gun for Hire" starring Alan Ladd and Veronica Lake.
* There might be a lesser-known film with that title. You could try searching for it with more specific information (director, genre, etc.)
* Perhaps you're thinking of a different movie altogether? If you remember any other details about the film, like the plot or other actors, it might help narrow down the search.
Please clarify the movie title or provide more details so I can assist you further!
