— The 20th Century Fox film "Hidden Figures" tells the untold story of the African-American women who worked for NASA as "human computers" in the early days of space race.

The movie, which opened wide in U.S. theaters on Friday (Jan. 6), recreates the settings and portrays some of the real-life people who made it possible for the United States to launch its first astronauts into space. "Hidden Figures" takes its audiences into the behind-the-scenes work of the Space Task Group at NASA's Langley Research Center in Virginia and introduces them to mathematicians Katherine G. Johnson (Taraji P. Henson), Dorothy Vaughan (Octavia Spencer) and Mary Jackson (Janelle Monáe).

The film as a whole is a nod to NASA's early years, but the filmmakers also included several "hidden" tributes to other history-making individuals, iconic photographs and even a few authentic artifacts. Here are five space history "easter eggs" you might not catch in "Hidden Figures."

(Fair warning: Although none of the details below directly disclose the plot of "Hidden Figures," there are mentions of specific movie scenes that are minor spoilers.)

1. Hidden artist

Though "Hidden Figures" primarily focuses on the "colored computers," the African-American mathematicians are not the only trailblazing women celebrated in the movie.

In a brief scene that goes by quickly, astronaut John Glenn (Glen Powell) is shown posing with his Mercury spacecraft for a reporter's photo while a woman dressed in coveralls kneels beside the capsule holding a paintbrush and small can. The scene is based on a NASA photo showing Glenn with spacecraft logo artist Cece Bibby.

"That's one of my favorite easter eggs in the movie," said Bill Barry, NASA's Chief Historian.

Cecelia "Cece" Bibby, who died in 2012 at the age of 84, was recruited by Glenn to hand-paint the insignia on the outside of his Mercury spacecraft, Friendship 7. As such, she was the first and only woman to ascend the gantry and go inside the "white room" that surrounded the capsule on the launch pad.

In the movie, the scene is moved to inside a hangar, but otherwise is fairly faithful to the historic image, down to the McDonnell company logo on the back of Bibby's coveralls.

The scene also includes a second easter egg: the woman who portrays Bibby is Cyndy Powell, Glen Powell's mother.

2. 'Shoe-in' of a set

In its recreation of NASA, "Hidden Figures" includes sets that are based on real locations, like the Mercury Mission Control, but also features settings the filmmakers designed to make the movie more visually interesting.

"Langley was a series of red brick buildings, all with cinder block walls, and that is very good as a work environment but it is not necessarily the most interesting thing to look at when you are making a movie," stated production designer Wynn Thomas in an interview with collectSPACE.

One location used in the film however, perfectly combined authenticity with aesthetics: the wind tunnel where aspiring engineer Mary Jackson (Monáe) gets the heel of her shoe stuck in a grate before a test of the Mercury spacecraft.

The wind tunnel looked real because it was real.

"Fortunately, there is a Lockheed Martin facility in Marietta, Georgia that has a wind tunnel that they had not changed since they first built it, so it was period correct," described Thomas. "And we were very lucky, the timing was perfect for us, because they were about to fix it up — gut it, tear it up and put in a new one."

3. Want not, waste not

Most of the scenes in "Hidden Figures" that are presented as being at Langley Research Center in Hampton, Virginia, were filmed in Atlanta, Georgia, at Morehouse College and at area locations. But that does not mean that a bit of the real NASA facility did not make it into the movie.

"In the movie, when Johnson (Henson), Al Harrison (Kevin Costner) and Paul Stafford (Jim Parsons) are standing in the lobby discussing if Johnson can join them in a meeting, you can see in the background two paintings of airplanes," said Barry. "They originally hung in the main headquarters building at Langley."

Today, that building is occupied by the Air Force, which no longer wants them, so NASA was — and at last check, still is — planning to excess them.

"The paintings are of the history of aviation, starting with Icarus and going up to jet airplanes," said Barry. "It just so happened the filmmakers were looking for things to add an atmosphere of NASA to the set and I knew about the three paintings heading for disposal." (Only two paintings appear in the film as the third was damaged.)

"So they diverted them to the movie," he said, noting there was a lot of legal paperwork involved. "But actual paintings the were hanging at Langley do appear in the movie."

4. From photo to film

Two prominent props in "Hidden Figures" were pulled from archival photographs found in space agency's archives.

Thomas and director Ted Melfi pored through photos and film reels to find scenes they could insert into the film (like the April 1959 Mercury astronaut press conference, which they moved up to the early 1960s to fit their timeline), or to ensure details were correct (the filmmakers even asked if there were period photos of the Langley parking lot so they could match the cars and trucks, according to Barry).

For the Space Task Group, Thomas recreated two types of objects seen in iconic photographs.

"We saw the image of the full-size blackboards, so clearly that was an element that needed to be in that room. How else do you tell a story about math?" he said, referring to a 1961 LIFE magazine photo of NASA engineers ascending ladders to all work on the same tall blackboard.

Also in the room are several transparent nestled globes, which feature an internal sphere representing Earth and an outer sphere mapping the constellations and orbital paths.

"I wanted that globe after seeing a very famous picture of John Glenn. His face is right next to one of the plexiglass globes," said Thomas. "I felt that recreating that globe was a great way to center the movie [because] our story is all about getting around that globe."

5. Parting shot

The same globe, in smaller size, appears in Al Harrison's (Costner's) office (Harrison is a fictional character, loosely based on several real people, including Robert Gilruth, the head of the Space Task Group) and at the end of the film, on Katherine Johnson's desk.

NASA's archives include a few photos of Johnson at work at Langley, with a mechanical calculating machine and one of the globes adorning her desk.

"Look at the very last image of the movie, we recreate that moment," said Thomas.

The camera angle is different than in the photograph, but it captures the spirit and, for those who recognize it, almost blends "Hidden Figures" into the real history that followed.

"The research from NASA was very inspirational." Thomas said.
