The Short Films of Roman Polanski - 　　(1957) Morderstwo (A Murderer) 　　The camera shows us a door handle and the door's striker plate; from this angle, they form a cross. The door opens and in steps someone in a dark trench coat. He approaches a bed in the room, where a shirtless man sleeps. The intruder takes out a knife. His movements are without haste, but deliberate and efficient. Will his sleeping victim awake in time to offer resistance?
