Gangster and heist movies took off as a genre back in the 1930s. While films such as The Godfather, Goodfellas and The Departed are still popular in 2017, they are relatively recent movies produced in an era where technology has advanced massively. Still, it was as far back as the 1930s when gang and mafia-related films first started to gain the attention of the public in the United States of America.
One of the best gangster movies of all time is Little Caesar. A 1931 American pre-Code crime film, it centred on a hoodlum who rises through the ranks of organised crime until he reaches its upper echelons. The film was actually based on the novel of the same name by William R. Burnett and is more popular than the book. Received well by the critics, Little Caesar aptly portrayed the social situation at the time and is worth a watch even now if someone wants to get a picture of what life was in the 1930s.
