Paul Reubens Played A Sentient Spaceship In This '80s Sci-Fi Cult Classic Movie

Who would Darth Vader be without James Earl Jones' voice? Could the Iron Giant and Groot pull so hard on the heartstrings if they didn't sound like Vin Diesel? Voices like these are what turned good science fiction movies into great ones, and in the case of a cult classic from 1986, it was one of the best sci-fi vehicles of all time that also sounded like Pee-wee Herman.

"Flight of the Navigator" was directed by Randal Kleiser and followed young David Freeman (Joey Cramer), who gets whisked away by an alien spaceship on a wild adventure that chucks him eight years into the future. Luckily, he's protected by the ship's artificial intelligence, which David names Max, who acts as a co-pilot and ally in this fantastical adventure. When it came to picking the pitch-perfect voice for the movie's intergalactic whip, also known as a Trimaxion Drone Ship, Kleiser hired a mystery voice to bring Max to life. The task fell to the vocal talents of "Paul Mall," as the movie credits say, who gave us a friendly alien pal that felt like a predecessor to Rocky in "Project Hail Mary." However, it only takes a few seconds to hear him speak to know it was none other than comedian Paul Reubens.

So why the secrecy? What was the reasoning behind Reubens keeping a low profile for this otherworldly adventure? Well, according to Kleiser, it was all a bit of fun for the star, who was already riding high after his previous hit that would become a cult classic on its own. 

After the booming success of "Pee-wee's Big Adventure," anyone who didn't know Paul Reubens had likely gotten used to hearing his voice by then, thanks to director Tim Burton and his directorial debut. As a result, Reubens thought it'd be fun to keep his name on the next project he was part of in secret and go by an alias. Disney revealed during the film's 30th anniversary that Keiser confirmed he was all for the idea, comparing the alteration to another sci-fi that was slightly more serious than a ship telling us to "see you later, Navigator."

"Paul did not want to have his name used in this project because he wanted to stay low-key and have it be a surprise," explained Keiser. "Kind of like Matt Damon in 'Interstellar.'" Coincidentally, it would be the second robot Reubens would breathe life into for Disney that year, with the other being Rex on the Star Tours ride at Disneyland. 

Fortunately, unlike the now-closed theme park ride, "Flight of the Navigator" has stood the test of time as a cult classic that fans love, particularly for Reubens' unmistakable rasp as Max. However, given Hollywood's struggle to remake the movie, could anyone be good enough to step into the sound booth and give us a Max as likable as the original? As it stands, would-be director Bryce Dallas Howard hasn't announced any potential cast members, and there hasn't been much news on the project since 2021, so the late Reubens remains the one and only Max.
