- The directors of Snake in the Grass researched conventions of noir films such as characters, settings, themes, and narrative structures. - They incorporated many conventions into their film such as including gangster characters and using settings like offices, lounges, and streets. However, they challenged some conventions by making one character experience emotions like jealousy and betrayal rather than portraying them across multiple characters. - Through their opening sequence and other elements, they both followed conventions like using a flashback and murder mystery, and challenged conventions such as putting the title at the end rather than following modern title sequencing.
