The Young and Dangerous film series (traditional Chinese: 古惑仔) is a collection of Hong Kong films about a group of triad members, detailing their adventures and dangers in a Hong Kong triad society. The series is based on a popular comic book series known as "Teddy Boy". The series contributed a lot to the public image of triads and was condemned by certain quarters as glorifying secret triad societies. However, it was immensely popular in Hong Kong and spun 9 sequels and spin-offs. Its main actors and actresses have also became major stars in their own right.
