House of Cards greenscreen driving scenes

[Adam Goral]

I saw a BTS picture from the set of "House of Cards" where they were shooting some green screen car work. I am extremely curious to learn more about the interactive lighting boxes hanging from the sides and rear of the car.

Does anyone have any experience with this technique? I'm wondering if these boxes are rear projecting the plates or if they are instead banks of LEDs controlled from a dimmer board? I remember reading in another article about the show how they shot the background plates first to get a sense of what the lighting would be like and then I'd imagine matched it as best they could on the green screen stage.

 

Such a great show with fantastic and bold cinematography. If anyone has an insights to their green screen work, I'd be most appreciative.
