The usual suspects analysis- Tom Corbett

Opening scene
The lighting varies from the bright flame of the matches to the dark interior of the boat. The setting is mysterious, as it is poorly lit and the characters are hard to make out. The panning of the camera to the fire as it burns across the floor shows the danger/ importance of the fire, and links into the liquid seen gushing onto the floor.

The lighting is a key element as it hides the arrival's face. The camera is cleverly positioned so that we only see his body, such as the tracking when he walks down the stairs adds to the creating of an enigma as to the identity of the person. The introduction of the gun adds to the tension, as the mystery man prepares to shoot the other.

The focus on the cigarette as it falls onto the floor and the continued burning, combined with the subsequent shots of the arrival leaving add to the suspense as the danger becomes apparent.
