Dangerous Assignment was an action-packed Old Time Radio show airing from 1949 to 1953, featuring film actor Brian Donlevy as Steve Mitchell, a US special agent tasked with getting in and out of dangerous situations. Herb Butterfield co-starred as the Commissioner, who assigns missions to Mitchell, while Betty Moran played The Commissioner's secretary. The show took place in various exotic locations, with atmospheric music and skilled voice actors adding drama and suspense.

Dangerous Assignment was also adapted into a syndicated television series and an Australian radio series. While not as iconic as shows like Escape and The Third Man, Dangerous Assignment had a solid fan base and set the stage for future spy novels and films, such as Ian Fleming's first James Bond novel, Casino Royale, in 1952.
