The director of the first two Harry Potter films, Chris Columbus, gave an interview to Collider , in which he recalled the stress of filming. He felt the pressure of the whole world while working on The Philosopher’s Stone.
I knew that if I screwed it up, it would be over. You cannot ruin this book. So I had to go to the set every day with some sort of tunnel vision so as not to think about the outside world, and that was much easier 19 years ago before the internet.
Overall, Columbus revealed that he was anxious during filming and was very scared of being fired.
For the first two weeks I thought every day that I would be fired. Everything was fine, I just thought that if I did something wrong, if I screw up, then I will be fired. It was very annoying. On the set, I hid these emotions.
Columbus’ fears were unfounded as the film became a 2001 hit. On the set of Chamber of Secrets, he relaxed and felt more confident. After the first two films, directors Alfonso Cuaron, David Yates and Mike Newell took over the franchise.
The last film in the franchise, Harry Potter and the Deathly Hallows: Part II, was released in 2011. Now Warner Bros. is developing spin-offs “Fantastic Beasts”. The third part will be released in 2022.
Also in development is the action game Hogwarts Legacy, it will be released in 2021.
