The document summarizes conventions used to establish the genres of three films - Arlington Road, Black Swan, and an unnamed film - in their first two minutes. For Arlington Road (horror genre), it uses creepy music, close-ups, whispering, and high lighting to make audiences uncomfortable. Black Swan (thriller/drama/mystery) uses low lighting, intense music, dark camera movements to set a mysterious tone. The unnamed film establishes its genre through a ballet performance shown in a very dark way, making the scene mysterious.
