Apollo 10 1/2: A Space Age Childhood tells the story of a young boy growing up in the 1960s who has dreams of going to outer space during the height of the space race. The stylistically animated film, directed by Richard Linklater, captures feelings of the retro nostalgia of growing up in Houston and dreaming of the then-unknown worlds beyond the stars. But if you didn’t grow up in Texas during the ’60s, you still might be familiar with the voice actors behind the characters.

If you’re wondering who lends their voices to Stan, his family members and the space crew, look no further than our stellar cast guide to Apollo 10 1/2.

Jack Black as grown-up Stan

The hilarious actor lends his voice to the adult Stan as he recalls what life was like growing up in Houston in the summer of 1969. Although you don’t see Black on-screen in the film (we know, so sad), you will appreciate his colorful narration throughout its duration. You might recognize Black from the hilarious movies Nacho Libre, Year One and his first Linklater collaboration, School of Rock. And you can hear his voice as the panda Po in the 2008 animated film Kung Fu Panda.

Milo Coy as young Stan

Stan, the movie’s main character, is a young boy in elementary school who lives in Houston in the late 1960s. He has a wild imagination and is often wondering what it might be like to go to the moon. But when he isn’t daydreaming, he’s enjoying all the simple pleasures that Houston has to offer, like going to Astroworld and hanging out at the drive-in movie theater with his siblings. Young Stan is played by Milo Coy, and Apollo 10 1/2 is his first credited acting role.

Zachary Levi as Kranz

Kranz is one of the men who recruit Stan to train to be an astronaut and lead him throughout his journey to space exploration. Levi is one of the more recognizable actors in the cast, best known for starring in the film Shazam! and the TV series Chuck and for voicing Flynn Rider in Disney’s Tangled. 

Glen Powell as Bostick

Bostick is another character who helps Stan in his journey to space. And let’s be real — Stan needs all the help he can get, especially since he dreams of going to space. Bostick is voiced by Glen Powell, who appears in another space-centric film, Hidden Figures, the hilarious rom-com Set It Up and the upcoming Top Gun: Maverick.

Lee Eddy as Mom

Stan’s smoking, wisecracking mom is always there when her kids need her — whether that’s to corral them around the dinner table or to break up arguments over who gets the TV remote. Stan’s mom is voiced by Lee Eddy, who appears in We Can Be Heroes and Freeform’s Cruel Summer.

Bill Wise as Dad

Stan’s well-meaning dad, employed by NASA, is always on hand to support his family and the dreams of his kids. It doesn’t hurt that he works in a place centered on space, which certainly aids in Stan’s fantasies of traveling to the moon. Bill Wise, who can be seen in another Linklater film, Boyhood, voices Stan’s dad.
