One of my all-time favorite gangster films is "Hit The Dutchman", about the Jewish gangster "Dutch" Schultz.
The film isn't even running for 60 seconds before the young Schultz bites the nose off of somebody who calls him a "dirty Jew".
At his own sister's Orthodox wedding, he "borrows" the bridegroom "for just a few minutes", and then about an hour later carries the dead brother-in-law, riddled with machine gun bullets, into the Temple vestry, and dumps him like a bloody bag of garbage on to the floor where all the Chasidim are dancing & celebrating.
There's even a gangster of Lebanese descent named "Fatty" Abbadabba in this movie, and it's all based on truth!
