The document provides several ideas for thriller openings that meet common conventions of the genre. Terence's idea involves a serial killer who was neglected by his father, the President, and seeks revenge. Gulaid's idea shows an ominous man being followed by an unseen figure in a park. Rahib's idea depicts flashes of a police interview followed by shots of a man meeting a woman and knives to set up a rape scene. Henna's idea starts with a gunshot and blood, then shows a woman running in heels pursued by an unseen man, changing her appearance before visiting a grave. The document also lists conventions thriller openings often use like minimal dialogue, hints of characters, tense music and lighting, and an unsettling tone.
