In the Around the World in 80 Days (2004) movie, when Phileas Fogg meets the Wright Brothers in an American desert:
Orville: Mr. Fogg, my name is Orville Wright. This is my brother, Wilbur. We're big fans of yours. Fan's a strong word. Better way to say it's we got a lot of money riding on you to win your bet. We're gonna use our winnings to build this.
Wilbur: Orville, maybe now is not the time. Let me explain it to Mr. Fogg. Just one second. Forgive my brother. He's got his head up in the clouds. He's one of these dreamers who thinks man's gonna go swooshing around on the planet like a little hummingbird.
Fogg: Yeah, we're all gonna fly. He thinks so, too.
Wilbur: It's kind of sad. I'm sorry. He's kind of a moron. He's mastered the cable steering system. The drag-and-lift ratio.
Fogg: This is brilliant. Thank you.
From this conversation, it's clear that Wright Brothers had yet to invent the airplane.
But, later, when Phileas Fogg was crossing the Atlantic to reach London in time to win the bet:
Captain: Mr. Fogg. I'm sorry to say, we've burnt the last of the coal. But I've had a word with the crew, and all of them have agreed to burn their shoes.
Fogg: The effort is appreciated, Captain.
Captain: Unfortunately, we've gained a mere six hours. Even shoes cannot help us now. Must be something we can do.
Fogg (after seeing flying birds): That's it. I've got it. Birds.
Captain: Excellent idea! We'll burn birds!
Fogg: No, we'll fly to London. We follow the laws of physics mastered by the birds millennia ago and combine it with the Wright Brothers' steering system.
Captain: Most people would laugh at you. But not us. We care about you.
Fogg: Captain, I'm afraid I have to ask permission to dismantle your ship to build this machine.
After that, he really built a flying machine and reached London in time. But, I can't say for sure if the date falls before or after December 17, 1903. Maybe, Wright Brothers' first successful flight happened the day after they met Fogg, but I doubt it, because they didn't have money at that time to build the machine.
Do we have conclusive evidence to establish who invented the airplane first: Phileas Fogg or Wright Brothers?
I haven't read the original 1873 book by Jules Verne, but I am sure the quotes I have given aren't in the books because the author couldn't know about the cable steering system and Wright Brothers being inventor of airplane.
