Disney+ is celebrating the release of its new historical drama, The Right Stuff, and the core set of characters are based on real-life astronauts. Inspired by the 1979 book of the same name by author Tom Wolfe, the re-imagined tale was originally set to air on National Geographic before moving to Disney's streaming service. Will Staples notably served as the writer for the 8-episode series, and he co-produced alongside Leonardo DiCaprio.

The Right Stuff follows a group of test pilots chosen by NASA to form the first set of astronauts known as the "Mercury Seven." As part of Project Mercury, the men participated in experimental research as it involved spaceflight. The new TV adaptation goes even further by following the astronauts and their families after they become instant celebrities. With multiple seasons planned, The Right Stuff aims to document the journeys of these seven brave men during their remarkable, yet dangerous, careers.

The Right Stuff was first transformed into live-action in 1983 with a film starring Scott Glenn, Ed Harris, Lance Henriksen, and Dennis Quaid. Disney+'s version of the story blends a mix of notable TV actors with the purpose of portraying the real astronauts that made up the Mercury Seven. While not all could pass for their historic counterparts, some of the cast members share undeniable similarities.

Alan Shepard

Jake McDorman plays the role of Alan Shepard, the first American to ever reach space. Shepard was chosen as part of NASA's Mercury Seven team after a respected career in the Navy. Not only did Shepard pilot the first crewed Project Mercury flight, Mercury-Redstone 3, but he also went on to command the Apollo 14 mission in 1971. Before Shepard's time as an astronaut came to an end, he served as the fifth person to ever walk on the moon. Shepard officially retired from the Navy and NASA in 1974 before helping form the Mercury Seven Foundation. In 1996, Shepard was diagnosed with a form of leukemia and passed away from the illness two years later. McDorman previously appeared in shows like Limitless, Greek, and Shameless.

As the pilot of Mercury-Redstone 4 (Liberty Bell 7), Grissom became the second American to fly in space. Grissom then piloted for Gemini 3 in the mid-'60s as part of Project Gemini.

Two years later, Glenn resigned from NASA to turn his focus on politics before being elected to the U.S. Senate in 1974.
