ALBERT LEA — An Albert Lea native had a hand in the creation of the costumes on the latest Christopher Nolan movie, “Interstellar.”

Stacia Lang, daughter of Neil and Barb Lang, worked as a key specialty costumer on the film, now showing at CineMagic 7 at Oak Park Mall in Austin.

What that job title means is she worked to execute the vision of the costume designer, Mary Zophres, and Nolan, the director.

“Everybody has their role,” Lang said.

The 1982 graduate of Albert Lea High School said “Interstellar” was challenging because the astronaut suits were set at a nonspecific future date — something like 80 years — but the characters had lived their lives in outer space, so the suits had to look like they were 40 years old.

“Christopher Nolan was ever-present, unlike some directors,” Lang said. “How the astronauts looked was critical to the story for him.”

“Interstellar” stars Matthew McConaughey, Anne Hathaway and Jessica Chastain.

The film is about astronauts on the ship Endurance who discover a wormhole near Saturn and are able to surpass expectations of human travel. Meanwhile, Earth is no longer sustainable, and the wormhole is a means to save the human race by searching for habitable planets in other star systems.

Nolan is known for twisting, nonlinear plots such as “Inception.” He also directed the three latest Batman movies and helped produce “Man of Steel.”

“He’s the hot director in Hollywood right now,” Lang said.

In the fall of 1982, Lang went to New York to attend the Fashion Institute of Technology and learned design, sewing and illustrations skills, among other abilities. She went to school for fashion but quickly switched to costumes and, she said, soon realized she really enjoyed specialty costumes — not the everyday garb a character wears but the outlandish or unusual outfits.

She spent years making specialty costumes on Broadway before moving to Minneapolis in 1990 to make patterns for Prince and eventually designing costumes for the music star. She moved to Los Angeles in the fall of 1997. She had decided she didn’t want to design so much as make things.

A costume designer designs the costumes. The key costumer makes the vision happen by determining materials and delegating the work of the costumes.

“I love bringing costumes to fruition,” Lang said.

Lang has been a costumer or a key costumer for a long list of movies needing specialty work, such as science fiction and superhero tales. She has worked on the two “The Amazing Spider-Man” movies, “Man of Steel,” “Star Trek Into Darkness,” “Tron: Legacy,” “Hellboy II: The Golden Army,” “Fantastic 4: Rise of the Silver Surfer,” “Blades of Glory,” “Eragon,” “Superman Returns,” “The Chronicles of Riddick,” “X-Men 2” and several others.

Sometimes, she appears in the credits. Sometimes, she doesn’t. She said she doesn’t mind either way but considers appearing in the credits at the end of a movie as a bonus. She is in the credits of “Interstellar.”

Lang said her work often requires being detail-oriented. She had a role in figuring out how aspects of the astronaut suits would come together, such as the way the backpack attaches to the suit or the gasket for attaching the helmet. She said molded parts of the suit, such as the helmet and the chestplate, are subcontracted.

Most of all, she has to make sure the whole things actually is wearable.

“We need to make it work on a human body because ultimately, it is our responsibility to make sure it fits,” Lang said.

So did Lang see McConaughey and Hathaway? She saw them in screen tests but on-set costumers handled the outfits she made during shooting. Lang showed them how the suits worked and moved on to her next project, “Jupiter Ascending,” slated for release in February.

However, Lang has worked with stars before. She sometimes builds costumes for extras, sometimes for an array of cast members and sometimes just a single character. That’s what she did for Jeff Bridges in “Tron: Legacy.”
