Full Scale Styrofoam DeLorean Finally Takes Flight

It’s 2025 and we still don’t have flying cars — but we’ve got this full-scale flying DeLorean prop from [Brian Brocken], and that’s almost as good. It’s airborne and on camera in the video embedded below.

We’ve written about this project before; first about the mega-sized CNC router [Brian] used to carve the DeLorean body out of Styrofoam panels, and an update last year that showed the aluminum frame and motorized louvers and doors.

Well, the iconic gull-wing doors are still there, and still motorized, and they’ve been joined by a tire-tilting mechanism for a Back To The Future film-accurate flight mode. With the wheels down, the prop can use them to steer and drive, looking for all the world like an all-white DMC-12.

The aluminum frame we covered before is no longer in the picture, though. It’s been replaced by a lighter, stiffer version made from carbon fibre. It’s still a ladder frame, but now with carbon fiber tubes and “forged” carbon fiber corners made of tow and resin packed in 3D printed molds. There’s been a tonne of work documented on the build log since we last covered this project, so be sure to check it out for all the details.

Even in unpainted white Styrofoam, it’s surreal to see this thing take off; it’s the ultimate in practical effects, and totally worth the wait. Honestly, with talent like [Brian] out there its a wonder anyone still bothers with CGI, economics aside.

Thanks to [Brian] for the tip! If you have a project you’ve hit a milestone with, we’d love to see it, even if it doesn’t trigger the 80s nostalgia gland we apparently all have embedded in our brains these days. Send us a tip!

Three 3D printed, spring loaded contraptions sit on a wooden shield. There are arrow shafts connected to the end and a piece of monofilament fishing line extending away from them and through a small eyelet at the edge of. the shield.

How To Shoot Actors With Arrows Sans CGI

Today, movie effects are mostly done in CGI, especially if they’re of the death-defying type. [Tyler Bell] shows us how they shot actors with arrows before CGI.

Almost every medieval movie has someone getting shot with an arrow, but how do you do that non-destructively? [Bell] shows us two primary methods that were used, the pop up rig and steel pronged arrows. The pop up rig is a spring loaded device with one end of an arrow attached that pops up when a mechanism is triggered. [Bell] 3D printed his own version of the mechanism and shows us how it can be used to great effect on shots from the side or rear of the victim.

But what about straight on shots where the rig would be blatantly obvious? That’s when you get to actually shoot the actor (or their stunt double anyway). To do this safely, actors would wear wooden body armor under their costumes and arrows with two small prongs would be shot along a wire into the desired impact site. We appreciate [Bell] using a mannequin for testing before letting his brother shoot him with an arrow. That’s definitely the next level above a trust fall.

We even get a look at using air cannons to launch arrow storms at the end which is particularly epic. Looking for more movie magic? How about the effects from King Kong or Flight of the Navigator?

Movie Magic Hack Chat

Join us on Wednesday, January 20th at noon Pacific for the Movie Magic Hack Chat with Alan McFarland!

If they were magically transported ahead in time, the moviegoers of the past would likely not know what to make of our modern CGI-driven epics, with physically impossible feats performed in landscapes that never existed. But for as computationally complex as movies have become, it’s the rare film that doesn’t still need at least some old-school movie magic, like hand props, physical models, and other practical effects.

To make their vision come to life, especially in science fiction films, filmmakers turn to artists who specialize in practical effects. We’ve all seen their work, which in many cases involves turning ordinary household objects into yet-to-be-invented technology, or creating scale models of spaceships and alien landscapes. But to really sell these effects, adding a dash of electronics can really make the difference.

Enter Alan McFarland, an electronics designer and engineer for the film industry. With a background in cinematography, electronics, and embedded systems, he has been able to produce effects in movies we’ve all seen. He designed electroluminescent wearables for Tron: Legacy, built the lighting system for the miniature Fhloston Paradise in The Fifth Element, and worked on the Borg costumes for Star Trek: First Contact. He has tons of experience making the imaginary look real, and he’ll join us on the Hack Chat to discuss the tricks he keeps in his practical effects toolkit to make movie magic.
