Superman’s Fortress of Solitude: 6 Months Design, 16 Weeks Build, 242 Resin Crystals!

Beth Mickle, the production designer for the “Superman” film, dedicated half a year to conceptualizing the design for Superman’s iconic abode, the Fortress of Solitude, with an additional four months spent on constructing the actual set.

Director James Gunn opted for a tangible set for the superhero’s hideaway rather than relying on computer-generated imagery or virtual production techniques. Mickle, who previously collaborated with Gunn on “Guardians of the Galaxy 3,” described the Fortress as one of her most demanding projects. She expressed the immense pressure they felt to respect the original portrayal while ensuring it resonated well with the audience, as she discussed with The Bangin Beats. The concept recalls the Richard Donner movies where a crystal thrown into the earth sprouts a crystalline structure.

Mickle aimed to preserve the essence of the original Fortress while also infusing new creative elements into the set’s design.

In Gunn’s narrative, we see a familiar world where Superman, played by David Corenswet, and other heroes form the Justice Gang, an early version of what will evolve into the Justice League. This team includes Green Lantern Corps member Guy Gardner (Nathan Fillion), Hawkgirl (Isabela Merced), Metamorpho (Anthony Carrigan), and Mister Terrific (Edi Gathegi). They unite to confront Superman’s archenemy, Lex Luthor (Nicholas Hoult), portrayed as a villainous mastermind, while Superman also juggles his relationship with Lois Lane (Rachel Brosnahan), the star reporter from the Daily Planet.

The movie opens with a weakened Superman, unable to move and stranded in the snow, calling upon his dog Krypto for rescue. As they approach their destination, the magnificent Fortress of Solitude majestically rises from beneath the ice.

Mickle’s rendition of the Fortress introduces awe-inspiring updates, yet retains a sense of familiarity. The exterior scenes of the Fortress were filmed in Svalbard, Norway, a location chosen for its icy landscapes that perfectly mimic the chilly environment of the Fortress. Constructing it was a formidable task, involving the creation of 242 large, real crystals. Mickle pointed out that the only use of CGI was to animate the rising movement of the Fortress from the ice.

The crystals were crafted from resin, with Mickle humorously noting that they purchased all the resin available on the Eastern seaboard in 2023, which was more cost-effective than CGI alternatives.

Inside the secret base, robots, each referred to by number, tend to Superman’s injuries using solar rays. The computer dashboard, each crystal, and the floor were all physically constructed for the set.

Mickle shared a memorable moment when actor David Corenswet first saw the set. He approached the steps in his Superman cape, and expressed his admiration for the meticulously crafted set.

Regarding a potential sequel and future ideas, Mickle remained discreet, only offering a laugh and stating she wasn’t at liberty to discuss those plans.
