Borsalino
The film was based on real life gangsters Paul Carbone and François Spirito. Alain Delon found the story in a book he was reading about French gangsters from 1900 to 1970. He produced the film looking for a vehicle for him to co-star with Belmondo.,Featured in Tango Bar (1987),Borsalino Générique
Written and Performed by Claude Bolling,Jacques Deray, who directed gangster genre movies almost exclusively, has achieved his most popular success (in America) with this movie. It was a stroke to combine the two leading men in roles which were cut out for each of them. Credit for this must go (in part, at least) to Alain Delon, who produced the movie. The very catchy, and hummable music for this movie was by the prolific composer, Claude Bolling, who collaborated with Deray on other films.

My only carping criticism is the length of the movie. I feel that about 15 minutes could have been trimmed in order to keep it moving.,
