Prospect – Behind the Scenes – Ammo Chargers

Prospect, the film I worked on last year building and finishing props and sets, premiered nationwide and is now even available to pre-order on Blu-ray or on iTunes! With that, I’ve been given the okay to do a handful of behind-the-scenes posts about a couple of the things I worked on for the movie.


The first charger I built was a hand crank portable charger for Damon’s thrower (the same one I built a case for). I used a plastic housing from our junk bin and found a piece of old electronics that had a motor on it. I glued it into my box and then sealed up the sides.

I then cut and drilled out a piece of scrap aluminum for the handle shaft.

I attached a few other assorted connectors, made the handle out of EVA foam, painted it to match the thrower case, and then cut three clip channels out of EVA foam for the top (this was with everything done except for sealing and painting the EVA foam – unfortunately I don’t have a photo of the final look – but you can see it in the movie!)

The second charger I made was an external, more universal charger. The box as made from some pieces of scrap sheet metal and some pieces of MDF I cut down from scraps. On the top of the box are the ammo ports – The first 3 rows are for ammo clips we designed, 3D modeled, and I printed on my printer at home (we didnt have one in the shop). The back ports are for several tube style ammo we had on some of the weapons. I ripped all of those off of some old circuit boards we had (there were a ton of different sizes but these happened to match up in size to the ammo we’d already created).

Because this charger box was meant to be rugged for camp/travel use, I dirtied it up real good. I made sure to get a few splatters as if it had been dropped down into some mud too.

And then was told it was too blue and the director needed it to be less blue. Instead of starting completely over, I made a light wash with some acryclics and went over the entire thing. It changed the hue enough without really impacting the weathering.

I then connected a giant, long cable to it and on set, it was plugged into the merc’s ship. This is a photo I took of it on set, its much harder to find in the film but you CAN see it if you are looking
