Lighting effect question

[JZASMM]

Hi, Mr. Mullen. I was wondering what the best way to achieve this lighting effect would be, as in those beams of light coming out of the right side.

Looks like any powerful light shining through some window-like holes in the set, from a distance -- probably an HMI, due to the blue-ish color. The beams are not as parallel and sharp as you'd get from a Xenon (which they also used in some scenes, or a Molebeam projector).

Would I need to add haze to that, or would that happen naturally?

Yes, you need to haze a set to see the beams.
