Clark’s disguise is a lot more plausible if you consider that most people in Metropolis don’t think or believe Superman even has a secret identity to begin with. To them he’s just Superman 24/7.
Every time they read about him or hear about him he’s always off somewhere far away saving someone.
Why would they believe someone with all that power would be sitting right next to them?
It’s too ridiculous to be true.
It’s also similar to actors going out in public. A lot of them are able to fly under the radar simply because no one expects to see a well known celebrity slumming it with the rest of us. Bradly Cooper was on the New York subway and all he wore was a sweatshirt, sunglasses and a backwards cap.
No one realized it was him until much later. Michelle Obama went to Wal-Mart only a few weeks after the election when her face had been plastered everywhere. Once again her disguise was minimal. Just sunglasses and cap. Only the cashier recognized her when they asked for ID.
And finally think about Kenshin Himura
and Vash the Stampede.
When all their friends and allies first met them all they saw was an awkward and goofy dope who tripped over their own feet. And they all thought the same thing:
“No way this idiot could be Hitokiri Battousai/The Legendary Humanoid Typhoon.“
Clark’s glasses are only part of the act. His mild-mannered demeanor, some clumsiness, and a larger than life alter-ego do the rest.
how much do you think it frustrates the Joker that a man in a bat costume punching a clown should be the funniest thing in existence but everyone in Gotham has decided to take it seriously
Listen, I’m watching the animated Batman series for the first time and I just gotta make a real quick observation.
Millennials are all fucking reckless nihilists, so there’s definitely that one time in Gotham where Harley and Ivy hold up a bank and some twenty-something pops their head up from the floor like “Hey, Miss Ivy–no, don’t shoot me, I just have a question–I’ve been trying to grow roses and they’re just not doing well, I’ve tried everything”. Batman shows up ten minutes later to Ivy sitting on the floor and having a serious conversation with some random kid about soil nitrogen content and what gypsum content the Gotham area tends to have. Harley’s kicked back on the bank counter playing tiddlywinks with a roll of pennies while the hostages shoot nervous glances at each other and try to figure out if they’re gonna be shot for getting up off the floor. The twenty-something is still lying on their back and Ivy’s sitting next to him.
“Hey, Bats,” Harley says happily, and waves to him.
“Hello, Harley. Ivy, I don’t mean to interrupt, but you are doing something illegal here.“
“We didn’t even take any money, now be quiet, I’m explaining how to acidify soil.”
