I think the editing in JFK is incredible. The ability to use real footage and incorporate it into the film without skipping a beat is very impressive. I think the ability to do this relies on the ability of things like mise-en-scene and cinematography. Because the film looked and felt like it was during the 60’s really allows Stone to freely incorporate the old footage. Sometimes, It was even difficult to determine if the news footage was real footage from the time period or footage Stone created. Without the ability to make everything seems like it was in the 60’s I don’t think stone would have been able to incorporate this footage so easily. It gives the film a truly realistic vibe and feels like I am watching the story unfold as it happened in 1960
Playing off the realistic vibe, the editing also conveyed the mirroring of how one would recollect memories. The cinematography and the editing created a tense atmosphere where the “memories” converge into truth at certain points.
