The ship that the boss is on is the Don Anselmo (as seen on the bow). It was launched in 1945 as the MV Reeving Eye, a C1-M-AV1 type cargo ship for the U.S. Maritime Commisson for use in WWII. In 1946 it was sold to a private company and was Panamanian-flagged. After being sold and renamed a couple more times, it collided with a Ecuadorian naval patrol boat on August 30, 1971 and sank with the loss of 13 lives.
The ship in the final sequence is referred to as the Higgins. John C. Higgins is the film's screenwriter.
"Lux Radio Theater" broadcast a 60-minute radio adaptation of the movie on
February 23, 1948 with Dennis O'Keefe reprising his film role.
Runs hand-in-hand with another Anthony Mann directed Film Noir also starring Dennis O'Keefe, Raw Deal; in fact, both are on the same "Anthony Mann Film Noir" DVD.
Included among the American Film Institute's 2001 list of 400 movies nominated for the top 100 Most Heart-Pounding American Movies.
