For 'Raging Bull' fans, you should check out the Jean Reno film 'Wasabi'. It is kind of like a comedic French Dirty Harry, where 2/3rds of the story is in Japan. Jean Reno uses the Raging Bull in Japan. First time I remember seeing that distinctive grip in a movie.
At the beginning he is using a S&W 686, I believe.
So, he prefers .357mag, not DH Callahan's .44mag.
Fun movie. It is French, but comes with a choice of either English subtitles or English sound track [and Jean Reno does his own voice for the English soundtrack].
Ok, now back to the topic at hand.
