The trailer for 'Double Indemnity' contains the following film noir conventions:

• Dialogue - typical of noir genre, fast-paced, back and forth
• Voiceover
• City location
• Character types - femme fatale, male patsy, investigator
• Narrative structure - an investigation, a confession at the beginning with flashback of events
• Lighting - lots of low-key lighting
• Enigma/mystery
• Dissolves/wipes/iris
• Smoke/cigarettes
• Sinister dramatic music
• Tagline references genre - 'murder'
• Stars associated with genre
• Director associated with genre
• Central character is sucked into a narrative
• Costumes typical of the genre
