The document analyzes conventions used in thriller, drama, and thriller/drama film posters. For thriller posters, consistent use of low-key lighting and body language hints like a character running imply fear. Drama posters rely more on realistic features through natural lighting and plain backgrounds to engage audiences. Thriller/drama posters combine conventions like complex backdrops from thrillers and mix of lighting from both genres to represent the balance of themes. Overall, the author concludes that film posters focus more on a film's unique themes than strict genre conventions.
