Thrillers commonly use props to support the plot and themes of violence and death. Props can range from everyday objects like phones to more violent weapons like guns and knives. Psychological thrillers will adapt the props to suit the personality of the antagonist, with more violent props indicating a more violent character. Examples include the swords used by antagonists in Kill Bill that were named and suited the culture. Common props in thrillers also include phones, money, computers, and briefcases to build tension, even if they are not violently used.
