How Did These Classic Movies Pull Off Stunning VFX?

Look, I see a lot of movies, and for some reason, I feel like VFX has either gotten lazier or maybe they're using too much green screen, but a lot of these things have this feeling of "we’ll fix it in post".

But when I watch old movies...sometimes they look better.

In a recent Film Riot breakdown, Ryan Connolly dives into the "Amazing Effects" of classic and modern cinema. I sat back and saw a lot of classic VFX that felt really good on screen.

So let's dive in and see what we learned, and what we can replicate.

Classic Movie VFX

The Power of Double Exposure (Faust, 1926)

One hundred years ago, F.W. Murnau was pulling off effects that still hold up today. To create the iconic "glowing eyes" of the demon Mephisto, the crew used a meticulous double-exposure technique that modern filmmakers have tried to replicate.

So, how did they do it back then?

• The Process: They shot the scene once, counting every single frame. Then, they rewound the film to the exact start point.
• The Trick: For the second pass, they blacked out the set and used a single, focused beam of light aimed at the actor's eyes, which were coated in reflective makeup.
• The Lesson: Precision is key. The actor had to hit his marks perfectly twice to ensure the glowing eyes aligned with his face. You can do all this in Adobe now, but it's cool to think about how much you need those precise movements and ideas to get what you want on set.

The "No-Mirror" Mirror Trick

I am a sucker for the "mirror" shot where the camera moves into the reflection. And in some movies, there isn't a mirror at all. In films like Sucker Punch and Terminator 2 , directors use a twin set so they can seamlessly put the camera anywhere with worrying about reflections.

• How it works: You build two identical sets side-by-side, separated by a sheet of clear glass (or nothing at all).
• The Coordination: Actors and their body doubles must mimic each other’s movements with frame-perfect synchronization.
• Pro Tip: In Sucker Punch , they actually dropped real mirrors into the frame during camera whip-pans to "lock in" the reality of the reflection once the complicated move was over. But in Terminator , it's just done to show a complex surgery. Look, you need twins to do this, but I find you could use body doubles and their backs and be fine.

Organic Horror

I am a massive fan of practical horror. I think we've come a long way in this area, but some of the best effects of all time, from things like Evil Dead nad Alien were done with practical builds and lots of the perfect blood recipe.

When Ridley Scott needed the inside of a Facehugger egg to look visceral and terrifying, he didn't reach for a mold-maker. He went to the fish market.

• The Material: The crew stuffed the Facehugger prop with clams, oysters, and mussels. Yes, this is nasty,
• Why it works: There is a "subconscious reality" to organic material. The way light hits wet, biological matter is incredibly hard to replicate with silicone or CG, even today. So when you have to make something, look to the actual physical traits you want and go get them in the real world.

The "Hand Double"

Okay, one of my favorite scenes in movie history is from Labyrinth, where you get the mesmerizing crystal ball juggling by David Bowie’s character, Jareth.

That wasn't movie magic or Bowie's secret talent. It was Michael Moschen , a professional juggler, stepping in.

• The Setup: Moschen crouched behind Bowie, sticking his arm through Bowie's cloak to replace the actor's actual arm.
• The Challenge: Because he was behind Bowie, Moschen was performing completely blind. It took weeks of rehearsal and countless takes to make the juggling look effortless. Most people don't have those resources, but again, this is thinking outside of the box. See how you can use multiple people to fix shots.

The $98 Million "Old School" Epic

When I was a kid, I loved to rent Cutthroat Island. This was before we had the Disney Pirates, and it was like an old-school swashbuckler that people dug.

While it was a box office flop, its practical effects were legendary.

• The Horizon Trick: To film sea battles without the danger of the open ocean, they built a shallow tank on the coastline. When filled, the water overflowed into the actual sea, creating a seamless horizon line. Fun practical solution to a bigger problem.
• The Switch: For the famous window-to-carriage jump, they used a "Texas Switch" combined with an early digital stitch. A stunt person fell into a pad, and the footage was digitally blended with a shot of the actress already in the moving carriage. Anyone can do this with the right camera moves and costuming, and I have seen so many indies pull this off.

The Bottom Line for Indie Filmmakers

As Ryan Connolly notes, "More expensive and complicated doesn't always mean better". And I like to think that with all of these studio movie solutions, there are some indie ways to do it that would pop even more.

The best special effects come from a willingness to think outside the box rather than just throwing money at a screen.
