- Robert Rodriguez made this movie solely for his children, based on an idea his son Racer had. Racer is given screenplay credit, and the main character is named after him (his middle name is "Max").
- Despite all their bickering and incompatibility, Lavagirl doesn't hesitate to save Sharkboy from the electric eels at the risk of her own life. When Max tries to stop her, she simply responds, "He's my best friend" and dives in.
- Similarly, when Lavagirl needs to be taken to a volcano to save her life, Sharkboy doesn't even bother to dignify Max's warning of, "You'll burn up" with a response. He just picks up Lavagirl and books it to the volcano, despite being weak to heat.
- When Max's parents reconcile after they realize they can't live without each other.
- Lavagirl thanks Sharkboy for saving her with a quick (but painful) kiss on the cheek. At the end, they try to hold hands, but as this hurts too much, they simply settle for touching fingertips.
- The implication that Sharkboy and Lavagirl are based on Max's parents.
- Max apologizing to Mr. Electricidad for imagining him as a bad guy. They both share a moment of understanding before returning to the crisis at hand.
- After Tobor gives Max and company a lift via his eyes and mouth (the only parts of his body that can move), we get this exchange.Max: I'm sorry I forgot about you, Tobor.
Tobor: Are you kidding? You just saved me! I'm free! (floats away happily)
