All these questions and answers are my favorite ones.

Catija's answer to How exactly are subtitles and closed captions written for movies? that shares quite nice details about subtitles that I was curious about.
Paulie_D's answer to Why did John Doe appear as press photographer?.
Gnemlock's answer to Has an actor ever played a woman, or an actress a man, in a non-comedic/horror way? asked by Ghoti and Chips.
Sinister's answer to Why is the movie titled "The Rum Diary"? asked by Chris Elvis. He gave a nice explanation of this movie title.
And last my own answer to the question How did they film the walks between the Twin Towers in The Walk?. It includes each detail about how this scene was filmed from different sources.
