Fans can be so demanding! Particularly if they're only 18 months old and haven't quite figured out yet that the hero on the screen is a fictional construct played by an all-too-human actor.
Welcome to Jaxson Denno's world. When the toddler's mom Heather discovered Robert Downey Jr. was filming "The Judge" near their Western Massachusetts hometown, she brought her son to the set and told him he was going to meet Iron Man.
And then he met a guy in jeans and a V-neck short-sleeved shirt -- who had actually shaved.
Denno told Boston.com, "I said to my son, 'Hey, here's Iron Man,' but he didn't have the red suit on so Jaxson put his hands over his face and got upset."
Click! went Mom's camera, and an iconic photo was created.
Still, Downey didn't take it too hard, said Denno. "He was amazing," she said. "You could tell he was a father. He was so sweet and nurturing."
