Actually Afraid of Spiders
The character of Ron is known for having a huge fear of spiders, so when it came to filming Harry Potter and the Chamber of Secrets with the giant spider Aragog, it was actually quite convenient that Rupert Grint has arachnophobia. He didn’t have to do much work to look terrified, which is quite the silver lining for having to work with a giant spider while filming.

Improvised Lines
Anytime the actors might have forgotten their lines, they improvised, and often they would add in some improvised lines to the actual scripts, creating a more natural feel for the characters. For example, when Tom Felton, who plays Draco Malfoy, said to his friend Goyle: “I didn’t realize you could learn,” this line was actually improvised and kept in the final cut.
