In this largely fictionalized film, agent Melvin Purvis is placed in charge of running down notorious killer Machine Gun Kelly and sets out to do just that. The film script is loosely based on Kelly’s actual 1933 kidnapping of an Oklahoma petroleum executive, but the names and locations are changed. However, the film does accurately depict Kelly as a weak man who is dominated by his ambitious wife.
Melvin Purvis: G-Man is a 1974 American TV movie about Melvin Purvis. It is a spin-off of Dillinger (directed by John Milius, co-author of the teleplay for this movie) and was followed in 1975 by The Kansas City Massacre, also directed by Dan Curtis and starring Dale Robertson as Purvis.
