The movie "El regreso de Al Capone" (1969) is a Spanish-Italian crime film. There appears to be some confusion, as there is no readily available information about a film with this exact title.

It's possible:

* The title is incorrect: There might be a slight variation in the title. If you could provide more details like the director or any other information you remember, that might help.
