As the world gears up for the release of the much anticipated Star Wars: The Last Jedi, it’s important to remember where the series came from. From a modern lens, the original trilogy may not seem too impressive, but the films utilized groundbreaking technology and filming techniques that would influence movies for generations.

We pay homage to the original Star Wars trilogy by looking at behind the scenes photos that capture just how groundbreaking the films really were:

Empire Strikes Back Luke Darth Vader

Behind the scenes of the iconic "I am your father" scene from The Empire Strikes Back.


Alec Guinness Birthday

Cast members celebrate Alec Guinness' birthday on the Tunisian set of A New Hope.


R2d2 And 3cpo

The actors inside the R2D2 and C-3PO costumes—Kenny Baker and Anthony Daniels—actually ended up as enemies in real life. Baker said of Daniels in 2009, "He looked down his nose at me like I was a piece of shit."


Stormtroopers

Rather than hire thousands of extras, Star Wars utilized matte paintings that create an illusion of a real environment.


Hydrating 3cpo

Actor Anthony Daniels came to resent his role as C-3PO, telling People magazine in 1983 that he "would have liked to smash the costume up with a sledgehammer."


Gamorrean

Carrie Fisher poses with a Gamorrean guard, one of Jabba the Hutt's lackeys, on the set of Return Of The Jedi.


Filming At Ats

Inspired by Paraceratherium, the largest land mammal in history, AT-ATs were filmed using stop-motion animation that produced their mechanical gait.


Hoth

Despite freezing temperatures during filming in Norway, Harrison Ford, Carrie Fisher and Mark Hamill enjoy a laugh.


Obi Wan Kenobi

Prior to joining the cast of Star Wars, Alec Guinness was a renowned theater actor. Though he referred to the script as "fairy tale rubbish," he would go on to call A New Hope a "staggering spectacle" after his first viewing of the film.


Dagobah

Although Dagobah appears to be an Amazonian landscape, these scenes were captured entirely in a London studio.


Chewbacca And R2d2

The actors behind Chewbacca and R2D2 take a break onset.


Darth Vader And Luke Skywalker

Luke Skywalker's epic fall was, in reality, broken by a pile of mattresses.
