Tell me about projectors and shooting

It's been many years, since probably 2006 that I have shot video BGs created with video projectors. My producer and I have an idea that we want to edit together some sequences
from our documentary and use a video projector to project the video outdoors at night and shoot the results. The last time I tried this, it worked pretty well, but those projectors in
2006 were just getting cheap. They weren't very bright, but they were bright enough when used in a dark room with talent lit in a separate zone to avoid the video lighting bleeding
onto the screens (we used 4x6 white foamcore). That was indoors in a studio.

The shoot we want to do will be outdoor and we will be projecting the scenes very abstractly with lots of weird angles over irregular surfaces, onto some small sheds and some boats.

Questions:

1. What is an ideal relatively small but powerful projector we could rent to do this? There are no mains in this location so I will bring my Honda EU 2000 generator, that's all I have for a power source.
2. Not that color accuracy is paramount but how would you white balance your camera to the projector so the colors are at least not tinted too badly?
3. We'd like to see that we are in a boatyard at night so we may do some supplemental lighting to kind of light up the areas around whatever we are projecting onto, carefully flagging the light off of the areas
that we are projecting onto. All I have are some Arri 650s, 300 and 150, lots of LED panels, two are daylight only and three are bi-color. Don't want to get into renting HMIs or anything like that
but it's seeming like perhaps a couple of Aputure 120Ds or 300s with barndoors would work? We'll be projecting ontopweirdly shaped surfaces so abstract is expected, we want to keystone and warp the images and embrace the abstract qualities.

The inspiration is sort of the James Bond opens where they projected images onto women's bodies and BGs. Any advice from those of you who have tried this trick is appreciated.

There used to be a big fan cooled ellipsoidal light that had an LCD panel in the pattern projection slot, went looking but didn't find anything. Maybe this will give some ideas and help you find a solution.
 
Last time I did this was around 2012, & according to the Callsheet we rented from a company in Glendale called Matrix Visual.

Thanks Bern, I'll check them out. It's a lot of trouble for probably just a title sequence but when I used to do it, I kind of went nuts with it, I think I bought half a dozen projectors and started getting very abstract with my foam core BGs. I miss those days, having a studio every day to play in.
 
The projector should be like a normal monitor, the color temp should be around 6500K.

Even inexpensive projectors are pretty good, nowadays. We shot video onto two people the other year for a sizzle/hype deal and the projector was just a little cheapy that someone probably picked up at Office Depot for a few hundo, max, but we were inside with no ambient light fighting it, either.
 
Curious about this also. Been wondering about projecting backgrounds behind talent for closeups. Resolution shouldn't be an issue if they're blurred in the depth of field.

Yeah, we may end up buying a cheap one over renting a high end one. We want to go really abstract and make it look very impressionist so having a super clear, ultra bright image isn't really the idea. Thanks for the color temp tip too!
