Trivia

The Dead End Kids terrorized the set during shooting. They threw other actors off with their ad-libbing, and once cornered costar Humphrey Bogart and stole his trousers. But they didn't figure on James Cagney's street-bred toughness. The first time Leo Gorcey pulled an ad-lib on Cagney, the star stiff-armed the young actor right above the nose. From then on, the gang behaved.

Because of the controversy over gangster films, the film was banned outright in Denmark, China, Poland, Finland, and parts of Canada and Switzerland.

To play Rocky, James Cagney drew on his memories of growing up in New York's Yorkville, a tough ethnic neighborhood on the upper east side, just south of Spanish Harlem.. His main inspiration was a drug-addicted pimp who stood on a street corner all day hitching his trousers, twitching his neck, and repeating, "Whadda ya hear! Whadda ya say!" Those mannerisms came back to haunt Cagney. He later wrote in his autobiography, "I did those gestures maybe six times in the picture. That was over thirty years ago - and the impressionists have been doing me doing him ever since."

A montage features a shot of gangsters bombing a storefront. This shot is actually an alternate angle of the bombing of a store in The Public Enemy (1931).

For years, viewers have wonder whether or not "Rocky" Sullivan (James Cagney) really turned yellow as he was being strapped into the electric chair. Some have wondered if he was faking it in order to keep his promise to Father Jerry. When asked about the scene years later, Cagney says he chose to play it in such a way so that the audience could make their own decisions as to whether or not he was faking.

Some segments of this movie were remade and modified for the feature film Home Alone (1990) and its sequel. In the two movies, Kevin watches them as "Angels with Filthy Souls" and "Angels with Even Filthier Souls".

The moment in which Rocky forces a trailing hood to take his place inside the phone booth in the pharmacy to get killed was inspired by the death of New York gangster Vincent "Mad Dog" Coll. In the real incident, Coll was locked in a gang war with "Dutch" Schultz. During the war, Coll hid in an apartment above a pharmacy and would only come out to go into the pharmacy and call his girlfriend from the phone booth. Dutch found out about this and when Coll went to make his routine phone call, two of Schultz's gun men walked in and shot Coll to death.

An architect by the name of Lewis Pilcher designed the death house - it went into service in the early 1920s. The building is still there at Sing Sing. On Google Earth, zoom in on the prison, and look at the southwest corner by the river. The building with two wings and a diamond-shaped structure in the middle is the infamous structure.
