This is what the creators of La Casa de Papel don't tell you

Boom boom, hello chicos and chicas! Honestly, I've been a bit obsessed lately with the adventures of our Spanish friends Tokyo, Nairobi, Rio, Denver, Oslo, Stockholm, Palermo, Raquel (do we really have to say Lisboa now?), El Professor and the whole gang. The season is running like a charm again. And of course, every series has its little secrets, trivia, and did-you-know facts. Hmm, let's see what the creators are hiding from us. Five fun facts. Here they come.

1. The original idea was actually that all the robbers would have a terminal illness

Sounded very logical for a long time (and a perfect reason for a joint heist with such different types), until they realized it might actually become a muy grande success with muchos seasons. Well, that makes it a bit tricky then. Just Berlin it is. Poor him.

2. The series was originally broadcast on Spanish television

Netflix predicted a grand success, bought the footage, and cut it into a miniseries of two seasons. Season 3 is the first produced by Netflix itself. And yes, you can see that in the budget.

3. The character (and appearance) of Tokyo is secretly stolen

Ever seen the movie Léon, from 1994? In it, Natalie Portman plays the role of Mathilda, and hey: that tough chick with that impulsive behavior, that bob, that (just a bit too) short fringe, that choker around her neck, looks a lot like... Tokyo. Yes, the creators largely based the character Tokyo on another film character.

4. Now a little about ‘Bella ciao, bella ciao, bella ciao, ciao, ciao!’

Did you know that the Italian anti-fascist song was used during World War II as a sign of resistance against Mussolini? And the song is still used worldwide during uprisings.

5. Denver initially had no idea what to do with the ‘crazy’ laugh

Actor Jaime Lorente looked at the script next to his name and found the word ‘trashy laughter’ three thousand times. He had no idea what they meant at all, thought: you know what, I'll just put my own spin on it and that's how the ‘creepy laughter’ came to life. In interviews, Jaime is asked all the time to imitate it, and he gets really uncomfortable about it.
