1) The author's preliminary task involved filming a scene in a classroom setting with a spy retrieving a magical artifact. While the classroom provided challenges, an abandoned building would have been a better setting.
2) For the full film, the author chose a rundown prison in a forest, which better fit the action genre. The setting conveyed the film's themes of camouflage and vengeance.
3) Both films featured casual costumes to help characters blend in, which the author found effective for conveying stealth. Proper lighting and shot selection were also improved upon for the full film.
