That is indeed sometimes the case. Sometimes an object has another purpose. But when I’m watching a cheesy crime movie, if the cinematographer makes a point of showing a close up shot of a weapon, it’s a safe bet that the object is somehow going to figure in the plot. I notice with higher quality mysteries like Knives Out there are a lot of red herrings, not in the typical sense of intentionally misleading us, but trying to show how any crime solving process has dead ends on the pathway to the answer.
