- Ear Worm: "'Who's Johnny', she said, and smiled in her special way!"
- Freud Was Right:
Johnny Five: "Doctor Ruth says, 'Violence is ze expression of sexual frustration.'"
- Hilarious in Hindsight: In the Parental Bonus, the old couple worries about the "grass" they might have left in the glovebox. The state of Oregon has now legalized recreational marijuana as of 2015.
- Another one is Stephanie's "roach coach" all-natural food truck being treated as something a bit silly. Today, Portland, Oregon is world-famous for its variety of food trucks and the stiff competition among them.
- Memetic Mutation: "Number Five alive!" and "Need input!" most famously.
No disassemble, nooo disassemble, nooo-o-o disassemble Number five!...
- Mondegreen: Courtesy of Ben in the sequel. "You lost number Johnny 5? Now you stop fucking up..."
- One-Scene Wonder: The Los Locos gang from part II:
- Spiritual Licensee: The movies give out a vibe that they were either produced by Steven Spielberg or distributed by Disney (WALL•E would later take inspiration from the films' character Number Five for the main character of the Pixar film), even though they weren't.
- Strawman Has a Point: Skroeder is adamant about destroying Number Five at all costs and deliberately undermines and steps on the toes of others who are working on a less militant and violent approach. The truth is that the SAINT robots have MILITARY applications with a fully active laser cannon, you can even see the Oh Crap! look on their faces when they realize he can use it freely. While the audience gets the benefit of seeing how benign and childlike Number Five is, the team they send in do end up provoking Number Five into a laser response. At the time who knows what else might have provoked the same reaction.
Howard: Crosby, what is it going to do?
Newton: It's hard to say; it's malfunctioning. It might not do anything.
Skroeder: But it could decide to blow away anything that moves, couldn't it?
- Ugly Cute: Johnny 5.
- Values Dissonance: Fisher Stevens - a white actor - is playing Ben, an Indian character. Not much thought would be given to that in the 80s, of course, but try making that casting choice in the 2010s. Aziz Ansari pointed this out on his show Master of None, and then had an amicable talk with Stevens on the subject for the New York Times.
- Visual Effects of Awesome: The animatronics used for Johnny Five are still quite impressive, and they reportedly took up nearly all of the film's special effects budget on their own.
- The Woobie: Johnny 5, at times, particularly the scenes following him making the connection between "disassemble" and "dead".
