Practical effects from the '80s and '90s were built on real constraints, and those constraints forced some of the most inventive filmmaking ever put on screen. The results hold up decades later precisely because the crews had no easy way out.
Coming to you from Film Riot, this fascinating video breaks down exactly how several iconic effects sequences were actually built, shot by shot. The helping hands sequence in Labyrinth is a good place to start. The crew constructed a 40 ft vertical shaft covered in gray stretchy latex, then lowered actress Jennifer Connelly through it on a harness while over 100 pairs of custom latex sleeves filled the frame around her. Roughly 150 of those hands belonged to real puppeteers reaching through pre-cut holes in the latex in real time. To form the talking faces, puppeteers stacked their hands together, three people to a face, each controlling a different feature, all performing in sync to pre-recorded dialogue.
The Aliens Alien Queen started as a rough prototype built from black garbage bags, foam, and ski poles just to test whether the concept would even work. The finished puppet used hydraulics for large body movements and two internal puppeteers to control the four arms, giving the limbs that twitchy, organic quality that mechanical systems alone can't replicate. Off-camera operators handled the legs, tail, and secondary movements through rods, cables, and remote controls. Multiple head and neck assemblies were built, some tougher for action, some more detailed for close-ups, with intricate cable systems controlling the jaws, inner mouth, and lips with enough precision that the queen could snarl and breathe convincingly. That level of engineering is part of why Aliens won the Academy Award for Best Visual Effects.
The Paris asteroid impact sequence from Armageddon is where the engineering gets almost absurdly specific. The practical shockwave element alone required building a 100 ft sand island graded at roughly 8°, laying steel sheets as a foundation, then arranging about 6,000 ft of primacord in 80 concentric rings buried under a foot of sand and mulch. Those rings were detonated just 5,000th of a second apart using a custom computer-controlled relay system. The full detonation lasted four seconds in real time and was stretched to 15 seconds of screen time using high-speed cameras. The initial flash came from detonating aluminum powder. Paris itself was rebuilt in Maya using aerial and satellite imagery, with most buildings modeled as simple blocks with photographic textures projected onto them rather than fully detailed geometry.
The Titanic section covers how Cameron's team built large-scale miniatures, a near full-size exterior replica, and interior sets mounted on rigs that could tilt and drop into water tanks, with visible breath added in post because you obviously can't submerge actors in near-freezing water for real. The Die Hard sequences, including how the crew got Alan Rickman's genuine look of shock and how Bruce Willis wore silicone feet over his real ones to walk on broken glass, round out a video that's dense with specific, verifiable detail on how these shots were actually constructed. Check out the video above for the full rundown.
