DIRECTOR JEYMES SAMUEL, A DE PALMA FAN, SUGGESTED IT FOR WORK ON SPLIT SCREENS

Editor Tom Eagles was interviewed by /Film's Shania Russell about working on Jeymes Samuel's The Harder They Fall:
There are some really great split screen moments, like in that final battle or when we see the death of RJ Cyler's character and we get to see everyone's reaction. Are those things that were in the script or when did you decide to use those?Yeah, Jeymes always wanted to do those two split screen moments. The other one is on the train. That last one that you're talking about when RJ dies, he was very particular about what it was. So we worked really hard even in pre, we got to Santa Fe a couple of weeks early, we were cutting in Santa Fe, and I actually worked with the assistants just with stock pictures to try and get that right, to get the rhythm right.
So that was very specific and then the other one, which is Cherokee, LaKeith, talking through the wall to the General on the train, that was a little bit more like, "I want split screens here, you figure it out." I think he was specifically, he did want it to wipe on, and then I just had to figure out how to cut a scene where can see both sides. Which is a tricky thing for an editor because normally you're always directing the audience's gaze a little bit. With split screens you can suggest but you can't tell them exactly where to look.
Because LaKeith was so magnetic, I would use cuts to sometimes try and draw your attention over to the other side, we needed to see what was going on there. And the other thing that was tricky about that is LaKeith is a very fluid performer, so he doesn't say the same thing twice ever. So those things were not shot at the same time, when he was doing the general side, he didn't do all that stuff about "Dred Scott free," he didn't do the countdown at the end. So I had to find bits and pieces that I could play on the general side that made it look like they were part of the same conversation.
And then there were just fun discoveries, I found that we could also wipe off with the movement of the door. So that was really fun and Jeymes told me to look at Brian De Palma for split screens. He's a big De Palma fan so I went back and looked at "Dressed To Kill" and a couple other De Palma's, and "Carrie," to see how those worked.
