The CG sequence with the skeletons featured on the DVD was originally omitted from the VHS versions released in the US, for reasons unknown.

According to Helen McCarthy, The Professional was based on various Western action films the writers had used for inspiration. Ironically, the film's own influence can be seen in later Western films.

One of the earliest anime productions to use CGI. It did not become a common addition to the genre until the mid-90s with the advent of Macross Plus and Ghost in the Shell.

The film's English title was extended to include "The Professional" before the title character's name because Carl Macek - who wanted the films released by his company (Streamline Pictures) to appeal to anime fans and ordinary film-goers alike - feared that those unfamiliar with the manga would think that the standalone film was part of a series. The "Professional" title had previously been used by LEED Publishing and Viz Media's localization of the Golgo 13 story "The Argentine Tiger".

Those involved in Golgo 13: The Professional, are open about the western influence weaved throughout the films visual ascetics. But if you're a fan of music, you will notice how popular western music also influenced the music in Golgo 13: The Professional. Listen for the influence of Blondie's Call Me 2:42 in, for Feels So Good by Chuck Mangione 50:47 in and for Haunted House from John Carpenter's Halloween 101:56 in.
