That could be done with a Leko or ETC Source-4 Leko, probably with a iris in it though it may not be necessary if the lens alone gets you the circle size you need.  With a light that close and the beam so wide, it may be more than a 50 degree lens, like a 70 or 90 degree.

There are also theatrical projector units that will create such spots, like a Vari-Lite:

Also to see the beam you need some atmosphere to shoot through-- a hazer would be quite helpful.

It's a matter of taste how much you want; but basically you turn it on before you roll and let it fill the space until you're getting enough definition on your light beam. Then you shoot. It'll dissipate as you go, so you'll need to re-fill the space with it on occasion.

Based on the lack of blue hilation on the edge of the field, it look like a  26 or a 36; the 50's are really blue around the field (and also don't get as flat). The edge of the field also lacks the telltale "steps" of an iris in focus.

 

It also looks like it's coming from a balcony rail position, although not too far from the subject (the aperture of S4 lenses is about 6"; it looks smaller than that compared to his head size) . The ellipse of the field seems to be getting foreshortened by the perspective.

 

Is this a frame grab from something we could look at?

 

One man's opinion,

Yes, it could be a shorter degree lens (narrower circle) if it were farther away, it's hard to tell in the photo.  Though I find that a 19 degree lens doesn't create as flat and even a field.

Agreed. Have you played with the EDLT lenses? Pretty nice, and much higher contrast with patterns.

Dedo projection kit could probably do this.
